One of the biggest financial mistakes I made in my twenties was walking away from a property I bought at 22. It was a strategic foreclosure; I wasn't struggling to make the payments. I just didn't see the point in continuing to pay for a home that had lost nearly half its value during the Great Recession. At the time, it felt like a logical business decision.
But looking back now, that same property I bought for $400,000 is worth over $1.1 million.
What that experience taught me is this: the market is always moving. It goes up. It goes down. But it rarely stays the same. What matters most is your ability to stay the course, to stick with your decisions, stay disciplined, and play the long game. Walking away felt smart in the short term, but in hindsight, commitment would have paid off more than any shortcut ever could.

Underestimating the long-term cost of small lifestyle debts is a common mistake. I fell into the trap of thinking that just a few purchases on a credit card were no big deal because the minimum payments felt manageable. This included occasional flights, nights out, birthday parties, and tech upgrades. However, that mindset kept me in a cycle of revolving credit card debt that quietly eroded my ability to save and invest meaningfully.
One critical lesson I learned from this mistake is that it is not always the size of the debt that causes the most harm; it is the normalization of carrying it. The real cost is the loss of opportunity and time. I missed out on many years of compounding returns and financial freedom because I was busy paying high interest on things I no longer owned.
The key takeaway I'd share with young adults is simple: don't just think about whether you can afford the payment, think about whether the purchase you want to make aligns with long-term financial goals. If the answer is no, skip the purchase.
Always remember that every penny has a job, and the earlier you take that seriously, the more options you will give your future self.

I neglected to maximize my 401(k) match for a couple of years immediately after college. It would have been easy to do, and I could have afforded it financially, but I didn't simply because I didn't care enough. Consequently, I left free money on the table.
What I didn't realize was that I was essentially stealing from my future self. Due to compounding, money invested earlier is worth more later. So even if it's a smaller amount because you're just starting your career, it will have outsized gains over time.
Now, I have to compensate for the money I didn't invest when I was younger by contributing higher amounts. It's a lesson I wish I had learned when I was younger because I would have tried to balance my lifestyle over time, rather than just optimizing for the present.

This isn't specific to me, but a mistake I often find people in their early twenties make is chasing hot stock tips without proper research. Some people jump fresh out of school, full of confidence, and think they can outsmart the market. It's usually not the case.
I've heard of people who invested in trendy tech companies that were getting a lot of buzz online, but they don't take the time to understand the fundamentals or whether those businesses have a real path to long-term success. Those investments often tank, and they must learn a hard lesson about speculation versus sound investing.
This experience is unfortunate, but hopefully it teaches young people the importance of having a strategy grounded in discipline and long-term thinking. Emotion and hype should never drive investment decisions. For me, through my own experiences, I've realized that real wealth is built over time through patience, diversification, and a clear understanding of risk. For young adults, my advice is simple: don't try to get rich quickly. Learn the basics of budgeting, saving, and investing early. The compounding effect of smart decisions made in your twenties can be life-changing. And always, always understand what you're investing in. It's okay not to know everything but not to invest in something you don't understand. Your future self will thank you for being thoughtful now.

A big financial mistake I made in my early twenties was buying a nicer car than I needed. This led to larger-than-necessary car payments and less money in savings. Conversely, my roommate purchased an old car for $1,000 and began his path to saving for retirement. He was wise in this instance; I was not.

I wish I had learned to cook earlier so that I could have eaten more homemade meals. Preparing dishes for yourself with grains, beans, vegetables, and protein is incredibly affordable. However, many people are accustomed to the flavors of prepared restaurant food and end up overspending as a result.
