Ready for Summer? Here are 8 Beachy Business Reads. Okay fine, they're not exactly beachy. But every entrepreneur should read these books, and all the better if you do it while catching some rays.

With warmer weather and vacations on the horizon, it's time to think about which books you'll be reading at the beach or by the pool this summer. The slower pace and long days offer a great opportunity for entrepreneurs to get ahead and gain an advantage on competitors.

Nearly all experts agree that the most successful entrepreneurs never stop learning. When asked how he learned to build rockets, Elon Musk simply replied, "I read books." Warren Buffett offered a more detailed response when he said, "Read 500 pages… every day. That's how knowledge works. It builds up, like compound interest. All of you can do it, but I guarantee not many of you will do it."

Want to learn something new this summer? Here's a list, in no particular order, of the top eight books that every entrepreneur should read.
