The Most Important Thing About Investing is to Start

Stock market basics for beginners

Hi, I am Richard. On this blog I share my thoughts, not investment advice. This is not a recommendation to buy or sell securities.

Mistakes and Lessons Learned

If I could go back to 2016, I would tell my younger self one thing: start investing immediately. I saved money for years but only began investing in 2022. In 2016, I did not have enough information, I did not know my options, and I did not know how to start. No one taught me about investing at school or at home. I started studying this field in 2021 after seeing an interview with Radovan Vávra, a former director of a Czech bank. He explained how simple the math behind investing is, which was a big surprise to me. Even elementary school children could understand compound interest and what is an ETF tracking a global stock index. It baffles me that these concepts are not taught in Slovakia. Just show these two things in math class, calculate a simple example, and that is it! Our whole society could be richer.

MSCI World Index
So far in 2024, the MSCI World index has returned an average 11.75 %.

The Basics of Investing: Compound Interest 10 %

Let me explain it as simply as possible. Imagine you have two piggy banks. Every month, you put $10 into each piggy bank.

Piggy Bank 1: No Interest

This piggy bank just keeps your money safe. Every month, you add $10. By the end of one year, you have saved $120. If you kept doing this from 1980 to 2024 (44 years), you would have saved $5,280.

Piggy Bank 2: With Interest

This piggy bank is special. It not only keeps your money safe but also gives you extra money every year for keeping your money there. This extra money is called "interest." Let us say this interest is 10% per year.

After the first month, you have $10. After the second month, you add another $10, making it $20. At the end of the first year, the piggy bank adds interest, so you get more, like $120 + 10% = $132. This keeps happening every year.

Summary

$10 a month for 44 years: $5,280 without interest, over $80,000 with compound interest at 10%. The MSCI World index averaged 11.75% through 2024. The math is accessible to a child. My biggest regret is not starting earlier.

Common questions on this article's topic

What is compound interest and why is it so powerful?
Compound interest means earning returns on your returns. In the article, this is illustrated with two piggy banks: putting 10 dollars a month into savings for 44 years yields 5,280 dollars. The same amount invested at 10% annual compound interest grows to over 80,000 dollars. The difference is entirely due to compounding. Each year's interest earns interest the following year, creating exponential growth over time.
How has the global stock market performed over the long term?
In the article, the MSCI World Index (covering 23 developed countries) is cited as having returned 11.75% year-to-date in 2024, while over the long run it has historically delivered roughly 8-10% a year in US dollars, presented as the core argument for starting to invest early. Even modest monthly contributions, compounded at this rate over decades, produce substantial wealth, which is why the article argues that the most important thing about investing is simply to begin.
Why is starting to invest early more important than investing large amounts later?
Because compound interest needs time to work. In the article, the biggest regret described is not starting to invest in 2016 when saving began, and instead waiting until 2022. Six years of lost compounding can never be recovered. Starting roughly ten years earlier can, at similar contribution levels, outweigh starting later, which is why beginning early often matters more than the size of the early contributions.
Why is not compound interest taught in schools?
In the article, this is highlighted as a significant gap in education, particularly in Slovakia. The math behind compound interest is simple enough for elementary school children to understand: show two scenarios in a math class, calculate the difference, and the lesson is clear. Research confirms that financial literacy levels in Slovakia are below the EU average, and Slovak institutions such as the National Bank of Slovakia have long promoted stronger financial education in schools.

What Determines a Stock Price?

In April, in the first part of this series, I wrote about an AI prediction system I had started building on my own machine. At the time the software was a few hours old and the prediction record was empty. The record since then has shown one thing: the system does not yet understand the market it is being asked to forecast. It can pull macro context, book value, earnings. But it cannot put those together into something that helps it understand the price.

Where the Money Goes When AI Takes the Work: Mapping the AI Economy

Prague, 13 May 2026. On my way to work I started thinking about something that stayed with me for days. If most routine work on a computer disappears in the next ten years, and a large share of repetitive manual work disappears with it, what happens to the flow of money? Who pays whom for what? Which economic layers will exist, how large will they be, and what relationships will run between them? This is the six-layer map I sketched as an answer.

Can AI Predict the Stock Market? Building a Calibrated System

I am building an AI system to predict the S&P 500. It runs on my own machine, uses free public data (yfinance, FRED, the Shiller dataset), and grades every forecast against reality. This series documents the build itself: the decisions, the methodology, the mistakes. What I will eventually share from the running system is a separate question, and an honest one.

What opened my eyes was the accessibility. I installed it in one prompt, free, and it runs entirely on my machine, sending data nowhere.

Which Work Will AI Not Replace?

Seventy per cent. That is where the first AI output begins, even when you give it the full company context and the best examples from the past. We are talking about the kind of output that cannot be defined programmatically. It is more complex. Often it is creative work. On one repeated type of output I reached eighty per cent within a week. Every further percentage point is harder than the one before.

What is the dead internet theory? Will we return offline?

For a long time we treated the internet as the main road. The place where work and relationships happen. Yet most of what we see on it today is, or soon will be, AI-generated: text, images, profiles and comments. The internet is turning into an online game full of bots, where you cannot be sure that a human is on the other side of anything. So I ask: was the online world the main road, or only a temporary detour that part of us will return from, back offline?

I know the other side too: professionals who automate everything that can be automated.

Europe Is Not Ready for Drone Warfare

Europe does not have the capacity to face a full-scale, mass drone war of the kind we see in Ukraine. Three dependencies weaken it: China supplies the physical material for defence systems, the United States supplies capabilities Europe does not have, and twenty-seven states cannot agree how fast, or who pays. Rearmament plans exist, but they are being carried out slowly.

Can AI Replace Human Judgement?

AI produces the graphic, the newsletter and the product page faster than a person. What is left for the one who used to do it is the judgement, knowing whether the output is good. But most people have worse judgement than AI. And whoever cannot judge quality cannot delegate either. How do you tell whether yours is the judgement a company relies on, or the kind it can replace?
