Sunday, Apr 6, 2025 12:23 pm ET
Mark Cuban, the billionaire entrepreneur and investor, has a straightforward message for those aspiring to join the ranks of the wealthy: find something you are good at, perfect it, and then learn how to sell it. This advice, delivered with his characteristic bluntness, encapsulates the essence of his investment philosophy and business acumen. Cuban's journey from a student living off macaroni and cheese to a billionaire investor is a testament to his strategic planning, disruptive technology investments, and unwavering focus on understanding customer needs.
Cuban's first rule, "find something you are good at and then perfect it," aligns seamlessly with his broader investment philosophy. He believes that mastering a skill or area of expertise is the foundation for success. This principle is evident in his investments in disruptive technologies, such as his early involvement in the streaming media revolution with Broadcast.com. By identifying and capitalizing on emerging technologies, Cuban has consistently demonstrated his ability to recognize and invest in companies that disrupt traditional business models.

Cuban's second rule, "learn how to sell whatever service or product you have mastered," reflects his approach to understanding customers and their needs. He emphasizes the importance of putting yourself in the shoes of the person you are selling to, stating, "In business you’re always selling – to your prospects, investors and employees. To be the best salesperson put yourself in the shoes of the person to whom you’re selling. Don’t sell your product. Solve their problems." This customer-centric approach is a key aspect of Cuban's investment strategy, as seen in his investments in companies with disruptive technologies and strong fundamentals.
Cuban's third rule, "always be learning new things," is a reflection of his belief in the ever-changing nature of business. He advises investors to stay informed about new technologies and trends, stating, "The beautiful thing about technology is that it changes every day…. On the day that it is released, you are as knowledgeable about that technology as anyone else in the world. From there it’s just about effort to keep learning." This continuous learning mindset is evident in his investment portfolio, which includes a mix of disruptive tech, crypto, non-fungible tokens (NFTs), small businesses, and S&P 500 stocks.
Cuban's fourth rule, "know your s* better than anyone else," is a testament to his strategic planning and execution. He believes that having a deep understanding of the market, the technology, and the customer needs is essential for making informed investment decisions. This principle is reflected in his investment portfolio, which includes a mix of disruptive tech, crypto, non-fungible tokens (NFTs), small businesses, and S&P 500 stocks. Cuban's ability to identify and invest in companies with strong fundamentals and innovative solutions is a testament to his strategic planning and execution.
Cuban's advice to the average investor is less about high-flying stocks and more about grinding away for every dollar: Live frugally, avoid credit cards, and buy toothpaste in bulk. Once you've saved some money, Cuban says, invest it in a low-cost index fund, preferably one that tracks the S&P 500. Then keep grinding, saving, and investing—and compounding will do the rest.
Cuban's financial advice for the average person isn't about or even the latest technology trends. It's about discipline, smart spending, and the power of long-term investing in an index fund. His advice boils down to simple but powerful principles: Live below your means, avoid debt, and invest with patience. By following these principles, anyone can build wealth and achieve financial success.
