Mark Cuban’s Favorite: Ayn Rand’s The Fountainhead

Mark Cuban loves The Fountainhead so much. As a matter of fact, he has a yacht that he named after the book.

Rand’s basic philosophy focuses on the individual’s power and pursuit of happiness that serve as the purpose of life.

According to Cuban, he picks up the book whenever he needs motivation. He even said that every single time he gets too far into the book, he gets too jittery so he’d have to put the book down. This book gives the billionaire goosebumps, which means it’s definitely worth reading.

Jeff Bezos’s Favorite: Kazuo Ishiguro’s "The Remains of the Day"

Jeff Bezos, CEO and founder of Amazon, is currently valued at $73 billion. This is why it’s somewhat surprising to learn that his favorite book is one that revolves around a servant’s life. In this case, the servant is Steven, the narrator of the book and an English butler.

The book’s setting is in post-war England. In the book, you’ll learn how the elderly butler deals with pivotal issues, as well as his struggle in maintaining the correct behavior. Emma Thompson and Sir Anthony Hopkins turned the book into a film in 1993.

Mark Zuckerberg’s Favorite: Virgil’s The Aeneid

This book recounts Aeneas’s legendary story. Aeneas was a Trojan who chose to travel to Italy. He then became a character of great political intrigue and respect on the battlefield. The book is considered as one of the classics of Italian literature. If you plan to read the book, you should know that it is a poem in dactylic hexameter. It has 9,896 lines.

Facebook’s CEO said that he came across the book while studying Latin. According to him, the book knows no boundaries with regard to greatness and history. Facebook employees say that Zuckerberg quotes lines from the book during meetings.

Elon Musk’s Favorite: Isaac Asimov’s The Foundation Trilogy

Business magnate, Elon Musk, is constantly working on bringing futuristic ideas into the present. Musk is known to provide award-winning electric vehicles, as well as Tesla solar power roofs.

Knowing that Musk’s favorite book series is a noted science fiction is not surprising. In the trilogy the fictional protagonist Hari Seldon spent his entire life developing ‘psychohistory,’ which combines mathematical statistics with sociology and history. The mathematician used mass action laws to predict events of the future. The science was able to predict Galactic Empire’s fall as well as a 30-year dark age.

Musk says that lessons of history suggest one fact: a civilization moves in cycles. He believes that there may be events that can cause a civilization’s progress to decline.
