Mark Cuban started with just $60 in his pocket before launching his first business, MicroSolutions, which he sold to CompuServe for $6 million. Five years later, the entrepreneur co-founded Broadcast.com, which Yahoo bought for nearly $6 billion.
Today, Cuban owns the Dallas Mavericks, stars on ABC's "Shark Tank" and is worth more than $3 billion.
If you asked the businessman about one of the he's ever made along the way, his simple answer may surprise you: Books.
"I used to love to walk through bookstores," Cuban tells Vanity Fair. "If there was something that caught me eye and I thought it could give me one idea — to spend $30 to give one idea that could help propel me and make my businesses better, it was a bargain."
One book in particular "used to get me all fired up," he continues: "The Only Investment Guide You'll Ever Need, " written by Andrew Tobias in 1978. Another particularly influential book helped him earn his first million, he says in an interview with Money: "Cashing in on the American Dream " by Paul Terhors.
Reading and thinking helps Buffett "make less impulse decisions than most people in business," he once said.
For Cuban, reading sparks inspiration, he tells Vanity Fair: "I'll read hours every day because all it takes is one little thing to propel you to the next level."
