What are the favorite books of CEOs such as Bill Gates, Mark Zuckerberg, Tony Hsieh, Elon Musk, Meg Whitman, and more? CEO.com recently compiled a list, shown in this infographic. As you can see, these CEOs read not just business books, but everything from fiction to history to biography.

CEOs must constantly evolve. One of my favorite parts of the job is adapting to new challenges and situations every day. CEOs who do this well are great learners. They have a voracious appetite for knowledge. While it can be challenging to keep learning on the job, CEOs must make time for it. They need to keep one step ahead and be innovative in their approaches to new products, services, hiring practices, sales, marketing, and every other facet of business.

This may explain why these CEOs read more than business books, beyond personal preference. As Albert Einstein said: “Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.”
