Nearly everyone would like to become wealthy. Not having to think or worry about money seems like a dream for most. One person in particular who’s achieved an epic level of wealth is Mark Cuban — American entrepreneur, “Shark Tank” star and part-owner of the Dallas Mavericks.
According to Forbes, Cuban has a real-time net worth of $5.7 billion as of March 2025. This is an incredible figure, and Cuban has done what most people think of as the impossible.
When you think of investing, the first thing that may come to mind is the stock market. While there’s always a level of risk, buying and selling securities can surely make you money. However, it’s not the only type of investment out there.
In fact, at times, investing doesn’t even involve money at all, and won’t cost you a penny. Here are some of Cuban’s best pieces of investment advice.
Invest in Yourself
In an interview with Men’s Health, Cuban explained that he’s a steadfast believer in one investment above all else: yourself. “Some of the best investments I ever made were investing in myself, first and foremost,” said Cuban.
When you’re first getting started in your career, you’ll inevitably face uncertainty. However, by investing in your education and skills, you can truly propel yourself to new heights that may otherwise be impossible to achieve.
Put in the Work
Hard work can pay off, and few people know that better than Cuban. He’s an advocate for putting in as much effort as possible. “What I learned early on is that if I put in the effort, I can learn almost anything,” said Cuban.
He explained to Men’s Health that even if it takes quite a long time to learn how to do something, it can pay off in spades for the rest of your life.
Keep Learning and Gain Knowledge
Another key point that Cuban stressed in his video interview was the importance of continuous learning, noting that the ability to learn is a skill in and of itself. “I recognized that learning was truly a skill, and that by continuing to learn to this day, I’m able to compete, keep up and get ahead of most people,” he said. “The reality is most people don’t put in the time to keep up and learn, and that’s always given me a competitive advantage.”
Additionally, in a recent post by Cuban on Bluesky, he explained that knowledge, once gained, can never be taken away and that by learning a skill, you can always generate revenue.
Perhaps this means periodically taking online courses to sharpen your existing skills and learn new ones. Continuous learning can help set you apart from others and get ahead of the pack. As the adage goes, knowledge is power. Cuban is a true testament to this virtue.
