Self-made billionaire Mark Cuban has consistently attributed his success, in part, to his devotion to life-long learning. In fact, the "Shark Tank" investor previously called it "the greatest skill" to have.
For Cuban, life-long learning means spending "four to five hours a day" reading, he told CNBC Make It in 2018. "I read everything I can. I don't care what the source is."
On Friday, Cuban shared in a tweet the two books he's currently reading:
By Katherine M. Gehl and Michael E. Porter
Written by Katherine M. Gehl, founder of The Institute for Political Innovation (IPI) and a former Overseas Private Investment Corporation (OPIC) board member (a role to which she was nominated by former President Barack Obama), and Michael E. Porter, a professor at Harvard Business School, "The Politics Industry" is a critique of the current political system.
"The Duopoly I would shut down in a nanosecond? The Democratic and Republican parties," Cuban tweeted on Wednesday. "Together they are the definition of anti-competitive collusion that has been successful shutting out competition in a manner that is detrimental to the American People every minute of every day."
Although Cuban's opinion was met with disagreement on Twitter, he called "The Politics Industry" a "great book" overall.
By Marco Iansiti and Karim R. Lakhani
In "Competing in the Age of A.I.," Marco Iansiti and Karim R. Lakhani — both are business professors at Harvard Business School — explore how artificial intelligence will transform the future of business.
"If you don't know A.I., you're the equivalent of somebody in 1999 saying, 'I'm sure this Internet thing will be OK, but I don't give a s---,'" Cuban said at the 2020 CES Conference in January. "If you want to be relevant in business, you have to or you will be a dinosaur very quickly."
In fact, Cuban has predicted that the world's first trillionaire will be an A.I. entrepreneur.
