How Cuban’s Reading Habit Took Off
Where It All Began
Mark Cuban’s reading habit started when he was building his first company, MicroSolutions, in the 1980s. Back then, he was solving tech problems for clients, often learning as he went. Instead of pretending to know it all, he read constantly to keep up.
In his own words:
“I read every book and magazine I could. Heck, $3 for a magazine, $20 for a book. One good idea that led to a customer or solution and it paid for itself many times over.”
That quote, from his book How to Win at the Sport of Business, shows just how seriously he took reading as a business investment. Books weren’t for entertainment. They were tools for growth.
Manuals, Markets, and Mindset
One of Cuban’s earliest “geek wins” came from reading the PC DOS manual, a technical book that helped him build custom startup menus for his customers. That small move made a big impact. It made MicroSolutions more useful to clients, which helped him grow and eventually sell the company.
Then came Broadcast.com. Cuban spotted the power of the internet before it was cool. His company streamed audio online before podcasts were even a thing. He sold it to Yahoo for \$5.7 billion in 1999.
Was this just luck? Not quite. It was deep knowledge. And much of that came from reading books, tech reports, and staying ahead of the curve.
Why Reading Was His Secret Weapon
What Readers Can Learn from Cuban’s Habit
Mark Cuban isn’t alone in using books as a brain weapon. But his results speak loudly. So, what makes this habit so powerful?
1. Reading Builds Problem-Solving Skills
Books give you access to other people’s ideas and mistakes. Cuban learned early that reading gave him shortcuts, insights he could test in real time with his own businesses.
2. Reading Helps You Spot Trends
From AI to quantum computing, Cuban reads for hours every day to stay ahead. In 2018, he told CNBC that he spends 4 to 5 hours daily on reading, diving into news, tech journals, and anything that expands his mind.
“In the tech industry, the only constant is change.” That quote shows how seriously he takes staying informed.
3. Reading Grows Empathy and Perspective
Cuban once told his kids:
“Somebody who doesn’t read lives one life. Somebody who reads lives an unlimited number of lives.”
Reading isn’t just about facts. It’s about understanding how people think, what drives them, and how to connect ideas. That kind of mental range helps with leadership, creativity, and decision-making.
Books That Shaped Him
Cuban has named several books that changed how he thinks. Some of his favorites include:
- The Fountainhead by Ayn Rand He read this multiple times and says it taught him to think independently and take full responsibility for his wins and losses.
- The Only Investment Guide You’ll Ever Need by Andrew Tobias He credits this book with helping him save and invest his first million.
- The Innovator’s Dilemma by Clayton Christensen Helped him understand why great companies fail, and how to spot disruption early.
These aren’t random titles. They reflect how Cuban used reading to understand business cycles, manage money, and build companies that last.
