Luca has €0 saved. By most measures he’s “not wealthy.” By one measure that matters enormously, he’s the wealthiest of the three characters in this course.
He has 47 working years ahead of him.
That’s the idea behind human capital — the present value of your future earnings — and it’s often the largest asset a young person owns, even when their bank balance says otherwise. Today’s lesson is about recognizing that asset, understanding why “invest in yourself” is the highest-ROI move of your 20s and 30s, and what that actually means in practice.
The two kinds of capital
Every person has two bundles of wealth:
- Financial capital. Money and assets: bank balances, investments, real estate, physical belongings, businesses.
- Human capital. Earning power: skills, experience, network, credentials, health, time remaining, reputation.
Most personal-finance writing focuses on financial capital. That’s fine for a 55-year-old. For a 25-year-old, it’s almost the opposite of what matters.
The human capital math
Your human capital is roughly the net present value (NPV) of your future earnings.
For Luca at 18:
- Expected career: 47 years (until age 65, ignoring FI).
- Expected average annual earnings (educated estimate): €35,000/year.
- Real growth rate: 1% per year on average.
- Discount rate: 5% real.
NPV calculation: approximately €700,000 to €900,000.
Luca’s “wealth” — in the broader sense that includes future earning power — is nearly a million euros. He doesn’t have the money yet. But the underlying asset exists and produces cash flows over time.
For Sofia at 28:
- Remaining career: 37 years.
- Expected average annual earnings (data analyst trajectory): €45,000/year.
- NPV: approximately €700,000 to €900,000 (similar to Luca because she’s earning more but has less time).
For Giorgio at 52:
- Remaining career: 15 years.
- Expected average annual earnings: €42,000/year.
- NPV: approximately €430,000.
Giorgio’s financial capital (house equity, some savings, TFR) is larger than his human capital now. Sofia and Luca are the reverse.
This flipping over time is the whole story of a career.
Why human capital declines and financial capital grows
Every year older you get:
- Human capital drops (fewer years left to earn).
- Financial capital (hopefully) grows (savings + investment returns).

A life that goes badly: you reach age 60 with human capital near zero and financial capital also low. That’s retirement poverty.
The savings-rate math from lesson 12 is precisely about how fast you convert human to financial capital.
Why young people should “invest in themselves” aggressively
Because their human capital is huge and their financial capital is tiny, improvements to human capital have enormous leverage when young.
Consider two investments Luca could make at 18, each costing €5,000:
Option A: Invest €5,000 in an ETF. At 5% real return over 40 years: grows to ~€35,000.
Option B: Invest €5,000 in a 6-month intensive course that raises his starting salary by €3,000/year. That €3,000/year over 40 years is €120,000+ (adjusted for career growth: often 2-3x). At year 1 alone, already 60% returned. Lifetime NPV: €250,000-400,000.
Option B wins by 10x or more. This is why “invest in yourself” is not a platitude — it’s the mathematically dominant strategy for young people.
For older people the math shifts. At 52, Giorgio has 15 years to amortize new skills. A €5,000 course that raises his salary €3,000/year for 15 years: €45,000. Still very good, but not the 10x of the 18-year-old.
What “investing in yourself” actually means
It’s not just paying for courses. In rough order of impact:
1. Skills that compound (lesson 15)
Technical, linguistic, and communication skills that multiply over a career. Learning English well. Learning data analysis. Learning negotiation. Each enables higher-paying work for decades.
2. Career moves (lesson 17)
Changing jobs strategically. The salary premium of switching companies is 3-5x the raise of staying. Each well-timed move compounds.
3. Network
People you know who can open doors. Not LinkedIn 500-connection-style. Deep relationships with 30-50 people in your industry who trust you. Most jobs, introductions, opportunities flow through networks.
4. Health (lesson 16)
A catastrophic health event destroys human capital. Preventive care (sleep, exercise, diet, screenings) is an investment with huge ROI.
5. Education
Formal degrees and certifications where they have ROI. In Italy, ROI varies wildly by field. Lesson 14 on education ROI covers this in depth.
6. Specific career assets
A professional license (like OCF for financial advisors, or abilitazione for teachers). A portfolio. Published work. Patents. These become permanent career capital.
When “investing in yourself” is a scam
Not everything is worth paying for. Red flags:
- Expensive “courses” from influencers promising life transformation. If it cost €2,000 and was advertised by someone on Instagram, skeptical default.
- MBA costing €80,000 with vague career trajectory. If your employer won’t pay (and tier-1 programs usually have sponsors for good candidates), the math often doesn’t work in Italy.
- “Certifications” that your target industry doesn’t value. Check with actual working people in the field.
- Pyramid schemes disguised as “passive income education.” If enrollment depends on recruiting others, run.
The test: who benefits from the “investment”? If the answer is “the course seller,” be careful. If the answer is “your future self, measurably,” proceed.
Human capital as the biggest risk too
The other side: if your human capital is your main asset, things that damage it are the scariest risks.
Disability. Chronic illness. Long-term unemployment. Industry obsolescence. These destroy human capital and they destroy it at the exact moment you needed it most.
Mitigations:
- Disability / income protection insurance (polizza invalidità/infortuni). Italian SSN covers basic disability, but gaps exist, especially for freelancers and high earners. A private policy costing ~€30-80/month can replace income for years if you can’t work.
- Diversify skills and industries. Someone whose only skill is being a coal miner in a region transitioning away from coal is highly exposed. Keep adjacent skills fresh.
- Emergency fund (lesson 9). For the short disruptions.
- Invest in health preventively.
- Avoid letting skills atrophy. Regular learning keeps you employable in a changing market.
The “human capital allocation” perspective
Treat your career as a portfolio decision. Where you invest your time is analogous to where you invest money.
- Current job: your “core position.” Produces cash flow now.
- Side projects / freelancing: diversification. Different industries, different risk profiles. Can become a main job someday.
- Learning/skill-building: “R&D budget.” Doesn’t pay now; pays later.
- Network building: “options.” Don’t pay off unless activated, but when you need them, they’re priceless.
Sofia works full-time (core position), freelances occasionally on weekends (diversification), is learning Italian business-side skills to move into financial analysis (R&D), and keeps in touch with people she met at university (options). That’s a well-allocated human-capital portfolio.
Luca’s version: full-time student (R&D), part-time job (cash + industry exposure), learning English aggressively (high-impact skill), staying active in school clubs (network).
Giorgio’s version: full-time teacher (core, stable), private tutoring on weekends (diversification), reading history seriously (R&D, enjoyment), maintaining colleague relationships (options).
All three are doing something right.
What to do with this lesson
Three things:
- Estimate your human capital. Rough is fine. Expected lifetime earnings, divided loosely by (1 + discount rate)^years. The exact number doesn’t matter. The order of magnitude often surprises.
- Think about where you’re invested most. If you spend 40 hours/week at work and 0 hours on skill-building, you’re concentrating 100% in your current role. Like any concentrated investment, that’s risky.
- Allocate at least 2 hours/week to human-capital investment. Course, book, skill practice, networking coffee. Small weekly input compounds over a career.
