If you're looking for something to read this weekend, consider recommendations from some of the world's wealthiest, most successful individuals.

Below, CNBC rounded up three books that Mark Cuban and other self-made billionaires say helped them get to where they are today.

Bill Gates

"Business Adventures" by John Brooks

The co-founder of Microsoft first heard of this 1969 classic from his long-time friend Warren Buffett. That was in 1991. Today, Gates still says it's "the best business book I've ever read."

While a lot has changed in the business world since the 1960s, the fundamentals of building a strong business have not, Gates says: "Brooks's deeper insights about business are just as relevant today as they were back then."

As for the key takeaway? "There's an essential human factor in every business endeavor," writes Gates. "It doesn't matter if you have a perfect product, production plan, and marketing pitch; you'll still need the right people to lead and implement those plans."

Mark Cuban

The "Shark Tank" judge and owner of the Dallas Mavericks became a billionaire back in 1998 when he took his online audio streaming company public, and Cuban says Terhorst's book helped him earn his first million.

Partly that's because it taught him to live well below his means from an early age.

"I did things like having five roommates and living off of macaroni and cheese, and I was very, very frugal," Cuban tells Money. Even when his career started to take off, he continued to focus on saving for the future and stuck to his frugal habits: "I didn't have a car that cost more than $200 until I was 25, I think. It was crazy."

Jack Dorsey

"The Art Spirit" by Robert Henri

The co-founder and CEO of Twitter and Square says the takeaways he gained from Henri's book about painting "helped me get started."

Among other lessons, Dorsey learned that to be successful, you need a specific purpose. "Without motive, you will wobble about," the billionaire entrepreneur reads from the book at a 2013 Y Combinator Start-up School event.

"If you don't have motive, if you don't have purpose that is shared between everyone, you will wander about," he continues. "You will wobble and you will not do anything of infinite means, you will not do anything that is timeless."
