The Algebra of Wealth

I like his blog; let’s see if the book is worth it.

I get why some might not like him. Scott has a strong personality, and I do not identify with a millionaire with a media empire, but he writes very, very well. I would recommend this book to anyone who wants to understand why building wealth matters, and he also explains how to do it, without frills. He is wealthy, he does not hide it, and he explains why, including talking about his failures. A very, very good book.

4.5 stars. Some passages are really too much (like when he talks about buying a private jet), and I do not like the idea of working relentlessly without a social life. Otherwise, I devoured it.

Notes

• 🔑 How do you achieve economic security? Slowly… There are 4 macro principles, Wealth = Focus + (Stoicism x Time x Diversification)
• Stoicism is about living an intentional, temperate life in and out of work. It is about saving money, for sure, but also developing strong character and connecting with a community.
• Focus is primarily about earning an income. As I discuss, income alone will not make you wealthy, but it is the necessary first step.
• Time is your most important asset. It starts and ends with an understanding of the most powerful force in the universe: compound interest.
• Diversification is our take on the traditional personal finance questions, a roadmap for making sound investment decisions and for being an educated participant in the financial marketplace.
• Financial security does not depend on what you earn but on knowing what is enough for you. It is about acquiring assets, not income, so they generate more wealth in turn.

Stoicism

• He cites Atomic Habits: “Your identity emerges out of your habits.”
• Great advice: “do hard things.” You need to challenge yourself and work hard to improve your position in this capitalist world. And you need a purpose.
• The “hedonic treadmill”: we struggle to feel satisfied, so we keep wanting more. That is why a precise goal matters, not “more money.”
• There will always be someone richer, and the richer you become, the more money you think you need to feel satisfied. A 10,000 raise when you earn 10,000 is fantastic, but to feel the same at 100,000 it takes far more effort.
• The truly important part is relationships, not money and career. Quoting Seneca: “There is no enjoying the possession of anything valuable unless one has someone to share it with.”
• 🔑 Do not take others’ mistakes personally. They may be having a bad day. Cultivate indifference. That is the stoic way.
• Work out consistently.
• Collect advice from people around you. You do not have to follow it, but different perspectives are essential. In general (controversial advice), surround yourself with wealthy people.
• Align actions and intentions. Economic security comes from behaviors repeated over time, not from theory. Planning is not enough.
• Build character over the long term. It is your defense against human weakness and the temptations of capitalism.
• Slow down. Notice the automatic decisions you make every day. Before acting, remember: “I choose my response.”
• Acknowledge emotions. Anger, shame, and fear are normal. Do not suppress them, but do not let them drive your actions. Find healthy outlets.
• Train your habits. Identify the behaviors you want and use habit science to make them automatic.
• Act. Avoid analysis paralysis. Do not confuse planning with action. You will learn more from early attempts and mistakes than from theory alone.
• Seek rewards, but do not depend on them. Money and status motivate, but they are not enough for happiness. There will always be something bigger or more exclusive.
• Recognize the role of luck. We tend to take too much credit for success and blame circumstances for failure (or the reverse). Be aware of the bias.
• Sweat. Physical exercise correlates with health, success, and happiness. Lift, run, move. You will gain time through greater energy and productivity.
• Make good decisions. Study how you decide, review good and bad choices, and learn from both. You will regret missed risks more than taken ones.
• Do not do stupid things. Stupid actions harm you and your ecosystem. Success depends on your network and the health of your community.
• Seek guardrails and advice. Value people and structures that keep you grounded and offer alternative views, especially as wealth and power grow.
• Tip generously. You will get better service, feel better, and likely live longer.
• Spend time with wealthy people. They model money management, open opportunities, and raise your ambitions.
• Talk about money. Money is society’s operating system. Normalize talking about it: it is too important to avoid.
• Invest in your relationship. The most important decision is to team up with someone. Your partner is the key relationship in your life.

Focus

• 🔑 Great career analysis. Do not follow your passion; find where you are good and invest fully. Many careers are not flashy, and you can be a rare profile there. Example from show business: too many people willing to work for free to chase a dream.
• Direct your attention, time, and energy deliberately. Economic security is built over time by focusing on the most productive opportunities.
• Accept the need for hard work. Nearly every path to wealth requires time, energy, and sacrifice. Resenting this undermines focus and future satisfaction.
• Do not follow passion. Follow talent.
• Take time to find your talent. It is not always obvious, even to you. Put yourself in new contexts, listen to what others recognize as your strengths, and notice what sparks curiosity and enthusiasm.
• Aim for mastery; passion will follow. Enduring passion is the result of hard work, not the cause.
• Iterate. Try new things, take risks, and do not expect immediate success. “Overnight success” is almost always the product of years of work. Failure is raw material for success if you learn.
• 🔑 Find the beach with the biggest waves. Market dynamics matter more than individual performance: go where the opportunities are greater.
• 🔑 Build communication skills. It is always an advantage, often essential. Read fiction, watch films, learn to visualize information, and observe how great speakers engage audiences.
• Choose work for culture as well as fit. It is not enough to match your skills; the environment must suit your personality. Work with people who bring out your best.
• Look beyond the obvious careers. Management, technology, finance, medicine, and law can be great paths, but they do not guarantee happiness. Explore widely, from architecture to zoology, including “Main Street” business. Follow talent.
• Move to cities and show up at the office. Your twenties and thirties are for learning to work, pushing yourself, and expanding your network and worldview. Be around people as much as possible.
• Know when to quit. Perseverance is a virtue until it turns self-destructive. When you play the odds, quitting is also an option.
• Be loyal to people, not companies. Organizations are temporary structures, without memory or morals, and they will not be loyal to you.
• Prune hobbies. Extra-work interests are essential for happiness and fulfillment, but they can distract from focus. Choose carefully what to cultivate and let go of what no longer fits.

Time

• Investment basics, solid segment. Recommended for beginners; a pleasure to reread. He writes very clearly.
• 🔑 Value your time more than any other asset. You can recover money, not time.
• Understand the power of compound interest. Small returns, accumulated for years, become enormous.
• Watch inflation. It is the dark side of compound interest: money will be worth less in the future. Goals and strategies must account for it.
• 🔑 Be rationally obsessed with money. Track income, expenses, and investments without emotional involvement.
• Track actual spending. If you monitor one metric, make it real outflows: the money that truly leaves every day.
• Save every month, even a little. Saving is a muscle: it strengthens with training.
• Avoid rigid financial commitments. Great in relationships, risky in finance. Be wary of subscriptions, installments, and assets that require maintenance.
• Stabilize spending. Variability undermines control, and loss of control never reduces spending.
• Define a “head-above-water” budget. Set a realistic monthly minimum that includes annual and irregular expenses.
• Give your future self options. You will change in unpredictable ways: leave flexibility in your plans.
• Set concrete, near-term savings goals. Not “a million by 30,” but “€5,000 by October 1.” Daily decisions build big results.
• Make spending a conscious choice. If you are not drowning in debt, you do not have to save every euro. Especially when young, living matters.
• Split expenses into three categories:
  • Daily consumption: food, housing, clothing, transport, installments, regular bills.
  • Intermediate expenses: large occasional outlays (e.g., college, a home down payment).
  • Long-term saving: investments to fund future consumption. It is your financial security.
• Keep the intermediate fund in liquid, low-volatility instruments. When you need the money, it must be available. Avoid real estate, private shares, or high-risk investments for this bucket.
• Absorb the hits. Errors and surprises call for adjustments, not abandoning the plan. Nothing is ever as good or as bad as it seems.

Diversification

• Finance basics. Nice, a bit obvious, but always useful for building a foundation. He does not hesitate to state his view, and it is clear he knows the topic. The tax analysis is excellent; he is candid that taxes are necessary, and his goal is to minimize them. He also explains how.
• 🔑 Wealth comes from converting as much current income as possible into investments.
• 🔑 Taxes are everywhere: earnings, investments, spending. Every financial decision (including doing nothing) has tax implications.
• Turn income into capital. Capital is money put to work to create value. Wealth comes from investments, not just income.
• Study the economy. From companies to central bank rates, the economic environment influences all your decisions.
• Diversify to maximize returns over time, not to chase a big hit. Aim for steady, compounded growth.
• 🔑 Think of money as a time exchange. You sell time for money and use money to buy others’ time. Evaluate investments and purchases in hours of life too.
• Risk is the price of return. There is no investment without risk: make sure the potential return justifies it.
• Evaluate returns by probability and time. Money today is worth more than money tomorrow. Reliable promises are worth more than uncertain ones.
• Invest mainly in passive, diversified, low-cost instruments (e.g., ETFs). They offer diversification and transparent risk.
• Allocate a small slice to active trading (e.g., 20% of the first 10,000 saved). Experiment, learn by doing, and track costs, gains, losses, and taxes precisely.
• Buy a home at the right time in your life. It is forced saving and an important asset, but it is first a life-stage choice, then an investment.
• Watch fees. Even small fees, over time, erode returns significantly.
• Understand tax impact. You do not really understand an investment if you do not understand its tax implications.
• Plan taxes. Tax-deferred accounts postpone taxes; Roth-style versions pay now for tax-free later. The choice depends on your current and future situation.
• Discount emotions. They are useful, but in investing they can sabotage rational choices.
• Do not make day trading a hobby. If you want to do it, do it as a job. Otherwise you will lose money and, worse, time.
• Find something you are good at that the market pays for, and push hard. Spend less than you earn to build an army of capital that works for you while you sleep.
• Diversify to survive uncertainty.
• Keep a long-term perspective. Time will pass faster than you think.
