Expert Who Became a Millionaire at 28 Reveals the Four Most Common Habits Among Those Who Build Wealth on Their Own — and That Most People Ignore.
Most people believe that becoming a millionaire depends on luck, connections, or a high salary. But those who built their fortunes with their own hands say that the key lies in habits — and they are more accessible than they seem.
According to a finance expert who became a millionaire at 28 and spent 16 years studying the topic, four attitudes stand out. And about 93% of people ignore them.
1. Invest Consistently, Without Waiting for the “Right Moment”
Even in times of economic instability, millionaires maintain a pattern: they always invest.
-
The duel between Shein and Temu gained a new chapter in London, with accusations of mass copying, a dispute over suppliers, and an impact on global fast-fashion.
-
The small tax on online shopping items has become a billionaire giant: the tax on international online purchases is soaring, breaking records, and now leaves the government facing a decision that could affect the pockets of millions.
-
Compass debuts on the stock exchange with a billion-dollar IPO and reveals a gas giant that moves billions, controls distribution in Brazil, and could transform the energy sector.
-
A Brazilian goes to a cash-and-carry store, assembles a basic food basket with 13 products, and shows how much it costs to make a simple purchase in Brazil in May 2026
They don’t try to guess the best moment to invest money. When the market drops, they don’t panic. They see opportunities.
By automating their investments and focusing on the long term, they take advantage of the power of compounding.
Fear doesn’t dictate their choices. This contrasts with common behavior: many sell assets during a crisis and accumulate idle cash.
The recommended practice by this expert is clear: invest at least 20% of income, increasing this share over time.
This constant habit creates a solid foundation for financial growth over the years.
2. Have Multiple Sources of Income at the Same Time
Relying solely on the salary from a job is risky.
The advancement of automation, artificial intelligence, and globalization makes job stability increasingly uncertain.
Millionaires know this and diversify their income streams. Many have earnings from stocks, rentals, side businesses, royalties, financial investments, and consulting work.
Each of these sources acts as a safeguard.
If one fails, the others keep the cash flow active. This approach serves as a financial safety net.
And it doesn’t require millions to start: renting a room, teaching classes, or starting a small business are already viable paths.
The logic is simple: instead of relying on a single monthly paycheck, it’s ideal to build pathways that ensure varied income over time.
3. Always Assess the Opportunity Cost
Another habit among millionaires is to think in terms of opportunity cost.
In other words, they calculate what they are missing out on by making certain financial decisions.
A direct example: before buying a luxury car for R$ 300,000, they ask themselves how much that amount could earn if invested.
The same applies to leisure expenses. Trips and gifts are evaluated carefully. It doesn’t mean that millionaires don’t spend — but they prioritize long-term goals first.
Before major purchases, they ask themselves three questions:
- Will this appreciate over time?
- Will it help generate more income?
- Am I giving up something more important by spending this now?
This mindset helps channel resources toward smarter and more strategic decisions.
4. Truly Believe That They Deserve to Be Rich
In addition to practical habits, there’s an emotional element: self-confidence.
The millionaires who got there through their own efforts have an unwavering belief that they deserve wealth. For them, money is not exclusive to an elite. It’s something that can be created.
This vision generates action. They don’t hesitate to seek raises, start a business, or invest boldly.
If they make mistakes, they learn. If they lose, they start over. The central point is that they believe wealth is a construction, not a privilege.
According to the expert, many people fail to become wealthy because they think they don’t have what it takes. But just looking at the millions of millionaires in the world can change that perception. The question to ask shouldn’t be “Why them?”, but rather “Why not me too?”
The four highlighted habits don’t require an inheritance, luck, or an extraordinary salary.
They are simple yet consistent behaviors that shape how a person manages money over time. According to the expert, anyone can adopt this model — as long as they are willing to change their way of thinking and acting financially.
