Warren Buffett has been one of the most successful investors in American history, and for good reason. The Oracle of Omaha's measured and meticulous approach towards investing is one to be emulated, even if you're only putting in a tiny amount of money into the market. If you really want to get ahead financially, Buffett has plenty of good ideas, namely a bunch of investing mistakes to be avoided.
Here are 10 money mistakes Warren Buffett says are keeping Americans broke — and how you can avoid them.

Letting emotions drive your financial decisions
Remove emotion from your investment decisions — especially when markets get rocky. Markets don't move in straight lines, and dips are part of the journey. "Rule No. 1: Never lose money. Rule No. 2: Never forget rule No. 1," Buffett said.
That means doing your research and investing in companies that can weather corrections. Don't sell in panic when prices drop. If you can, remember: buy greed, sell fear.
Not paying off credit cards in full each month
Credit cards have notoriously high interest rates that can add up quickly and eat away at your cash flow. "Interest rates are very high on credit cards," Buffett famously said, "Sometimes they are 18%. Sometimes they are 20%. If I borrowed money at 18% or 20%, I'd be broke."
Avoid piling on credit card debt, or else you're setting yourself up for years of financial pain as the interest compounds every month.
Buying things you don't need
The wealthiest people manage their money, and they don't spend it on frivolous things to impress people and signal status. A lot of cash gets thrown away on unnecessary items, whether it's a fancy car or a massive house upgrade.
Buffett understands this idea well, which is why it's one of his central tenets: "If you buy things you don't need, you will soon sell things you need."

Not saving and investing early in life
Compounding interest takes a long time, and the sooner you start, the better. Start thinking of your investments in terms of decades, not years, and adopt a long-term approach to building your wealth.
"Someone's sitting in the shade today because someone planted a tree a long time ago," is a classic Buffet quote, and for good reason. You won't see any meaningful gains in your portfolio unless you continue to invest in it through upturns and downturns.
Investing in things you don't understand
If you can't explain how a business makes money, then you should not invest in it. "Never invest in a business you don't understand," Buffett once said.
If you don't understand the company, you will struggle to comprehend how the market values it. This can spell disaster for your portfolio, as many "fad" investments fall to the wayside and drop to zero.
Not maintaining an emergency fund of liquid cash
Staying out of crippling credit card debt means building up an emergency cash fund that you can easily access. Having more liquidity built in also gives you plenty of "dry powder" to invest in opportunities as they arise.
If you don't have the cash on hand to invest in a burgeoning industry, you could lose out.
Using leverage or "borrowed" money for your investments
Leverage is essentially borrowing money against your portfolio to buy more assets, and it generally does not end well. Once there's a big enough downturn in the market, you get cleaned out because you're over-leveraged, and you'll be out a lot of money.
Buffett says the two biggest pitfalls he's seen people fall into are debt and drinking — especially the dangers of borrowing too much money.
Treating investing as a fast track to wealth
The only way to get rich fast is by gambling — whether on cards or a risky company — and the odds aren't in your favor. Instead, treat investing as a long-term project, not a shortcut to wealth.
"Our favorite holding period is forever," is a Buffett maxim, and it makes sense. If you invest in companies with great products and strong management, the asset will, on average, continue to increase in value over the decades.
Overpaying for assets
Try to buy assets at fair value — overpaying can wipe out any competitive edge. This applies to everything from stocks to homes and cars. Buffett once noted that a company he thought had lasting strength lost its advantage within a few years.
The takeaway: research carefully and think long-term. If you don't truly believe in an asset's future, you're likely overpaying and risking losses.
Earn $100 cash rewards bonus with this incredible card
The Wells Fargo Active Cash® Card (Rates and fees) has no annual fee and you can earn a $100 cash rewards bonus after spending $500 in purchases in the first 3 months.
Cardholders can also earn unlimited 2% cash rewards on purchases.
The best part? There's no annual fee.
Trying to be perfect with your investments
The fact is, you're not going to win on every investment you bet on. The goal is simply to have more overall wins than losses. According to Buffet, "You only have to do a very few things right in your life so long as you don't do too many things wrong."
Focus on getting the basics right, and avoid doing anything impulsively or without proper planning. That way, you can steadily build your portfolio year after year.
Bottom line
Warren Buffett's timeless lessons on money boil down to patience, discipline, and common sense: qualities that don't require a million-dollar bank account to apply. His core message is simple: avoid debt, live below your means, and invest steadily in what you understand.
These habits, more than flashy purchases or big salaries, are the real signs of financial success. As Buffett himself proves, true wealth isn't about how much you spend but how wisely you use what you have. After all, he still lives in the same Omaha house he bought in 1958 for $31,500 — a reminder that smart choices, not status symbols, build lasting prosperity.
