You’re 25 years old, you have €1,500 saved, and you’ve read that “starting early is essential to benefit from compound interest.”

You open the first brokerage account you find, buy a global ETF, and suddenly you feel like an investor.

But wait a moment.

What if I told you that those €1,500 could potentially generate a return 10 times higher if invested differently?

I’m not talking about miracle cryptocurrencies or aggressive trading strategies. I’m talking about investing in yourself.

This is not motivational philosophy. It’s mathematics.

And in the next few paragraphs, I’ll explain why, for a young person with limited capital, investing in education and skills has a higher expected ROI than financial markets.

Before we continue, a disclaimer:
I’m not saying that investing in financial markets is wrong. I’m saying there is a logical order in financial decisions — and for many young people, education comes first.

The Myth of “Start Immediately with Any Amount”

Financial education in Italy has improved in recent years. More and more people understand the importance of investing, diversification, and low costs. That’s a positive development.

But there’s a problem: financial education is often confused with immediate financial action.

“Invest even just €50 per month — the important thing is to start!”
How many times have you heard that?

The message is well-intentioned, but incomplete. Because it hides a fundamental question:

Does it make sense to invest all your available capital in the markets if that capital is negligible compared to the income you will generate over the next 40 years?

Let’s look at a concrete example.

Marco, 24 years old, has €2,000 saved.

Scenario A:
He invests everything in a global ETF.
Expected real return: 5% annually for 40 years.
Result: approximately €14,000 (in real terms).

Scenario B:
He uses €1,500 to enroll in a programming course that increases his net salary from €1,200 per month to €1,500 per month.
In one year, he recovers the investment.
Over the next 40 years, that income increase is worth more than €140,000 in nominal terms (and significantly more in net present value).

Difference: 10x.

This is not an isolated case. It is the consequence of a well-established economic concept: human capital.

What Is Human Capital (And Why It Dominates Your First 20 Years)

The concept of human capital was developed by economist Gary Becker in the 1960s, work for which he later received the Nobel Prize in Economic Sciences in 1992.

In simple terms, human capital is the economic value of your skills, knowledge, and experience. It is your ability to generate income over time.

Becker demonstrated that investing in education and training is not merely a cost, but an investment with measurable returns (Becker, G. S., 1964, Human Capital).

Another key economist, Jacob Mincer, developed empirical models linking education, experience, and lifetime earnings (Mincer, J., 1974, Schooling, Experience, and Earnings).

What does this mean for you?

It means that between the ages of 20 and 30, your most important asset is not your financial portfolio. It is your earning power.

Think about this:

If today you earn €1,200 net per month and you work for 40 years, you will generate €576,000 in gross income (without even considering salary increases). That is your current human capital.

Now compare:

€1,500 invested in an ETF that becomes €14,000 in 40 years
vs.
An investment that increases your income by 20% for your entire working life.

There is no comparison.

The Numerical Comparison: €1,000 in the Market vs €1,000 in Education

Let’s run the numbers seriously — no storytelling.

Scenario 1: Financial Investment

Assumptions:

• Initial capital: €1,000
• Expected real annual return: 5% (conservative, after inflation)
• Time horizon: 40 years

Compound interest formula:
FV = PV × (1 + r)^n

FV = €1,000 × (1.05)^40 = €7,040

In real terms, you end up with roughly €7,000 of additional purchasing power.

Not bad.

But now let’s look at the alternative.

Scenario 2: Investment in Education

Assumptions:

• Initial capital: €1,000
• Current annual income: €18,000 gross (about €1,200 net per month)
• Post-training income increase: +15% (conservative for in-demand skills)
• Time horizon: 40 years

Annual income increase:
€18,000 × 15% = €2,700 additional gross income per year

Over 40 years:
€2,700 × 40 = €108,000 additional gross income

Even discounting to present value (using a 3% rate), we obtain approximately €62,000 in net present value.

The Ratio

€62,000 / €7,000 ≈ 8.8x

Human capital outperforms the financial investment by nearly nine times.

This is not an argument against investing in markets.

It is an argument about sequencing.

When capital is small and earning power is low, the highest-return investment is often the one that increases your income — not your portfolio.

But There’s More: The Income Leverage Effect

So far, we have only considered the direct income gain.

But there is a second-order effect that is even more powerful:
with a higher income, you save more.

Let’s return to our example:

• Income €1,200/month → 10% savings rate = €120/month
• Income €1,500/month → 15% savings rate = €225/month

Difference: €105 more per month to invest, for 40 years, at a 5% real annual return.

Result: approximately €161,000 in additional wealth.

Now the picture changes completely.

The investment in human capital does not just increase your income directly — it also multiplies your ability to accumulate financial wealth.

It creates a cascading effect:

Greater skills → Higher income
Higher income → Higher savings
Higher savings → Larger financial investments
Larger investments → Greater long-term wealth

This is why early-career decisions matter so much.

When you increase your earning power in your 20s, you are not just improving next year’s income.
You are reshaping the entire trajectory of your financial life.

Empirical Evidence: The Data Speaks Clearly

This is not just my personal opinion.
Decades of economic research confirm that investing in human capital pays off.

Returns to Education

According to the OECD (Education at a Glance, 2024), each additional year of education increases average income by 9–10% in developed countries.

In Italy specifically, the lifetime income gap between high school graduates and university graduates is approximately 25–30%.

Economist David Card of Princeton University estimated that one additional year of schooling increases earnings by about 10% (Card, D., 1999, The Causal Effect of Education on Earnings). His body of work on labor economics contributed to him receiving the Nobel Prize in Economics in 2021.

The conclusion is consistent across methodologies and decades:
education and skill acquisition generate measurable, persistent income premiums.

Upskilling and Reskilling

The Future of Jobs Report (World Economic Forum, 2023) estimates that by 2027:

• 44% of current skills will become obsolete
• 60% of workers will require reskilling
• Digital skills will carry a 20–35% average wage premium

Translated into practical terms:
those who continuously invest in their skills maintain — or increase — their market value.
Those who do not see their earning power gradually erode.

In a rapidly changing labor market, standing still is effectively moving backward.

Lifelong Learning

Research by James Heckman and colleagues shows that the returns to skill investment decline with age, but remain positive until roughly age 40–45.

In other words:

• Investing in education at 25 has a significantly higher ROI than at 45
• But even at 45, the return remains positive and economically meaningful

Timing matters — but continuous improvement always compounds.

The Psychology of the Young Investor

Now let’s address a less rational — but equally important — aspect:
why do so many young people rush to invest in financial markets even when it may not be the optimal choice?

The “Action Bias”

Behavioral finance teaches us that humans suffer from action bias:
we prefer doing something — even if suboptimal — rather than doing nothing.

You have €1,500 sitting in your bank account.
You see it idle. Inflation is eroding it.
You think: “I need to do something.”
So you buy an ETF.

But this reaction ignores a fundamental question:

What is the highest-return opportunity for that €1,500?

Investing does not necessarily mean buying financial assets.
It means allocating resources where they have the highest expected return, given your time horizon and personal objectives.

Financial Overfitting

Another common issue is what we might call financial overfitting:
optimizing irrelevant details while ignoring the main leverage points.

I constantly see discussions about:

• “Accumulating or distributing ETF?”
• “TER 0.12% or 0.20%?”
• “Physical or synthetic replication?”

With €2,000 invested, the difference between a 0.12% TER and a 0.20% TER amounts to €1.60 per year.
Over five years, maybe it pays for a pizza.

Meanwhile, investing €1,000 in a professional certification that increases your salary by €200 per month generates €2,400 per year.
Every year.
For decades.

The order of magnitude is completely different.

The Illusion of Control

Daniel Kahneman and Amos Tversky documented the illusion of control:
the tendency to overestimate our ability to influence random events (Kahneman & Tversky, 1979, Prospect Theory).

With financial investments, you feel in control:

• You choose the broker
• You select the ETF
• You decide when to buy
• You monitor the portfolio

But actual returns depend on global market forces over which you have zero influence.

With human capital investment, control is tangible:

• You choose what to study
• You decide how much effort to commit
• You immediately apply new skills
• You see the impact reflected in your income

This also reduces psychological risk.
It is often easier to tolerate volatility in your career — which you can influence — than volatility in financial markets — which you cannot.

When NOT to Invest (Only) in Education

That said, I am not claiming that investing in education is always the right choice.
There are situations where it does not make sense — and we need to be intellectually honest about that.

Education That Has No Market Value

Not all education has economic value.

A course in medieval philosophy may be culturally enriching, but it is unlikely to increase your earning potential.

A simple evaluation criterion:

Is the skill you are acquiring demanded by the job market?
Are companies willing to pay more for someone who possesses it?

If the answer is no, the investment may have personal value — but not necessarily financial return.

“Motivational” Courses Without Substance

The education market is full of overpriced programs that promise:

• “Financial freedom”
• “Winning mindset”
• “Change your life”

Yet they fail to teach concrete, monetizable skills.

Red Flags to Watch For:

• Vague promises (“transform your future”)
• No detailed syllabus
• Heavy focus on motivation rather than technical skills
• Generic testimonials without measurable results

If you cannot clearly define the expected economic outcome, you are not making an investment — you are making a bet.

No Market Demand for the Skill

Some skills may be valuable in theory but lack demand in your local labor market.

Example:
An advanced blockchain certification may have strong value in major tech hubs, but if you live in a small province with limited tech companies, the economic return could be minimal.

Human capital investment must always be evaluated within your specific geographic and professional context.

When Your Employer Pays for It

If your company covers training costs or allows you to attend courses during working hours, it makes little sense to spend your own money first.

Employer-sponsored education offers:

• Zero direct financial cost
• Lower opportunity cost
• Immediate practical application

Always exhaust these opportunities before allocating personal capital.

Criteria for Choosing High-ROI Education

So how do you select a human capital investment that actually makes sense?

These are the criteria I personally use.

Verifiable Market Demand

Ask yourself:

Are there job postings that explicitly require this skill?

Go to LinkedIn, Indeed, or other job platforms. Search for positions that list the skill you want to acquire. Look at:

• Number of job openings
• Required seniority level
• Salary range (when available)

If you find 50 openings for “Data Analyst with Python” and 2 for “Financial Reiki Expert,” the decision becomes obvious.

Market demand is the first filter. Without demand, there is no economic return.

Transferable Skills

The most valuable skills are transferable across industries and roles.

Examples:

• Programming (Python, JavaScript)
• Data analysis (advanced Excel, SQL, Tableau)
• Project management
• Effective communication
• Technical English

These skills are useful in almost any professional context and are less likely to become obsolete.

Transferability reduces career risk and increases optionality.

Barrier to Entry

There is a paradox:

The easier a skill is to acquire, the lower its economic value.

If it takes only 20 hours of YouTube videos to become an “expert,” supply will quickly saturate demand — and the wage premium will collapse.

Look for education programs with a moderate barrier to entry:

• They require time (months, not days)
• They demand practice and real-world projects
• They provide recognized certification
• Not everyone completes the program

Scarcity creates value. Effort creates scarcity.

Long-Term Upgradability

The best education teaches you how to learn.

A course that teaches you “the 10 most useful Excel functions” provides static knowledge.

A course that teaches you relational database logic and process automation provides meta-skills you can apply for decades.

In a fast-changing labor market, adaptability is the ultimate competitive advantage.

Fast Feedback Loop

Prefer education that allows you to apply the skill immediately and see measurable results.

Example:
You take an advanced Excel course and the next day you automate part of your workflow, saving two hours per day. Your manager notices. Your value increases instantly.

The shorter the feedback loop, the faster the return on investment.

The “Puzoy” Hybrid Approach: The Best of Both Worlds

I’m pragmatic, not ideological.

The best solution is not “all in education” or “all in ETFs.” It’s a strategic combination that evolves over time.

Here’s the framework I use.

Phase 1: Foundations (Age 20–28)

Absolute priority: Human capital

• 80% of available capital invested in education
• 20% in small financial investments (for learning)

Why keep 20% in financial markets?

• You learn how markets work
• You develop savings discipline
• You start building “emotional experience” with volatility

But the main goal at this stage is not turning €1,000 into €1,100.

The main goal is increasing your income potential.

Phase 2: Consolidation (Age 28–35)

Balanced allocation: 50% human capital, 50% financial capital

At this stage:

• You (hopefully) have stable income
• You’ve built solid core skills
• You begin accumulating meaningful capital

Now it makes sense to both continue upskilling and build a serious long-term investment portfolio.

Human capital still matters — but financial capital starts compounding meaningfully.

Phase 3: Growth (Age 35–50)

Shift in priority: 20% human capital, 80% financial capital

After 35–40 years old:

• The marginal return on education decreases (you’re already senior)
• Your income and savings are higher
• Compound interest starts working seriously in your favor

Now the priority becomes making accumulated capital work efficiently.

Education doesn’t disappear — but it’s incremental rather than transformational.

Phase 4: Preservation (Age 50+)

Focus: 100% financial capital + risk management

After 50:

• Human capital returns decline significantly
• Retirement approaches
• The objective shifts to preserving and growing wealth prudently

But there’s an important caveat:

This framework assumes you built strong human capital earlier.

If you reach 50 without market-relevant skills, you’re in trouble.

Practical Case Study: Laura, 26 Years Old, €1,800 Available

Let’s put everything together with a realistic example.

Profile

• Name: Laura
• Age: 26
• Current income: €1,300 net/month (permanent contract, small company)
• Total savings: €1,800
• Skills: Technical diploma + basic Excel
• Goal: Improve her financial situation

Option A: Pure Financial Investment

Laura opens an account with a low-cost broker. She invests €1,500 in a global ETF and sets up a €100/month automatic investment plan.

10-Year Projection

• Initial capital: €1,500
• Monthly contributions: €100 × 120 months = €12,000
• Expected real return: 5% annually
• Final portfolio value: approximately €17,500

Not bad.

But let’s look at the alternative.

Option B: Human Capital First

Laura allocates €1,200 toward:

• Online Data Analysis course (€600): SQL, Power BI, advanced Excel
• Google Data Analytics certification (€300)
• Portfolio projects on GitHub (€300 in software and time investment)

She keeps €600 as an emergency fund.

After 6 Months

Laura completes the course.

She applies her new skills at work:

• Automates monthly reports
• Builds dashboards for her team
• Proposes data-driven optimizations

After 9 Months

Her manager notices the added value.

She’s offered a Junior Data Analyst role internally at €1,600 net/month (+€300/month = +23%).

Alternatively, she changes companies with her upgraded CV and secures €1,700/month.

Year 1

• Income increase: +€400/month × 12 = +€4,800/year
• Initial investment recovered in 3 months
• Year 1 ROI: 400%

Years 2–10

Laura continues growing professionally.

By age 35, she reaches €2,200/month (a real income increase of roughly 70%).

With higher income:

• She saves €300/month instead of €100
• She invests in financial markets anyway
• She may afford a home earlier
• She enjoys greater economic security

10-Year Projection

• Cumulative income increase: approximately €50,000 (conservative estimate)
• Invested portfolio (started after Year 1): approximately €45,000
• Total wealth: €95,000 vs €17,500 in Scenario A

Difference: 5.4x

And this is still conservative.

With in-demand tech skills, Laura could realistically reach €2,500–€3,000/month in a large city or working remotely for international companies.

The Most Common Mistakes

Optimizing Percentage Returns Instead of Life Trajectory

The common mistake: optimizing the ETF expense ratio (0.12% vs 0.20%) on €2,000.

The math:
0.08% difference on €2,000 = €1.60 per year.

It’s irrelevant.

What truly matters is maximizing your lifetime financial trajectory, not squeezing marginal efficiency out of a marginal capital base.

When your capital is small, optimizing micro-costs won’t change your life. Increasing your earning power will.

Your First Investment Is Your Ability to Generate Income

You can have the most efficient portfolio in the world, but if you earn €1,000/month and spend €950, you’re going nowhere.

Conversely, if you earn €2,500/month and spend €1,800, you accumulate €700/month.
In 10 years, that’s €84,000 to invest.

With that kind of capital, you can build real wealth.

Human capital is the primary lever.
Financial investments are the secondary lever (still important — but secondary).

Get the order right.

Patience as a Competitive Advantage

Warren Buffett famously said:

“The stock market is a device for transferring money from the impatient to the patient.”

The same applies to human capital.

Investing in skills requires:

• Time (months or years before results appear)
• Discipline (studying instead of relaxing)
• Uncertainty (no guarantees of success)

But those who develop this patience gain a massive competitive advantage over those chasing shortcuts.

There is no overnight wealth — only compounding effort.

No Guarantees — But Probabilities in Your Favor

Just like financial markets, there are no certainties.

You can take an excellent course and struggle to find a job.
You can acquire skills and see the market shift.
You can do everything right and still face bad luck.

But the probabilities are on your side.

Decades of economic research show that, on average, investing in human capital pays off. Just as investing in diversified financial markets pays off on average over the long term.

Don’t look for guarantees.
Look for the highest probability of success.

When to Start Investing in Financial Markets

Now the practical question:
“Okay, I invest in myself first. But when do I start investing in the markets?”

The answer depends on your situation, but here are the criteria I personally use.

Criterion 1: You Have an Emergency Fund

Before any investment — whether in education or financial assets — you need an emergency fund covering 3–6 months of expenses.

This is non-negotiable.

Without an emergency fund, any unexpected event (car repair, job loss, medical expenses) may force you to liquidate investments at the worst possible time.

Stability comes before growth.

👉 If you want to go deeper: What an Emergency Fund Is and How It Works

Criterion 2: Your Income Is Growing Steadily

If your salary has been stagnant for years, your priority is still human capital.

When you begin to see growth — promotions, raises, role changes, improved career prospects — then it makes sense to allocate capital to financial markets.

Rising income creates investing power.
Stagnant income limits it.

Criterion 3: You Have “Meaningful” Capital to Invest

What does “meaningful” mean? It depends.

A practical rule of thumb:

When you can invest at least €5,000–€10,000 upfront, plus at least €200 per month consistently, it makes sense to start building a serious financial portfolio.

With smaller amounts, the impact is marginal.

I’m not saying you shouldn’t invest smaller sums — it’s useful for learning — but don’t expect it to transform your financial life.

Scale matters.

Criterion 4: You Have Time to Manage It

Financial investing requires time:

• Initial research and learning
• Opening a brokerage account
• Defining a strategy
• Basic monitoring
• Tax reporting (especially under self-declaration regimes)

If you’re in a life phase where every hour counts — intense studies, a demanding new job, small children — it may be wiser to postpone.

Opportunity cost applies not only to money, but to time.
