Shoe Dog by Phil Knight
This book is extremely inspiring. Be careful with this book though, because it will make you seriously question your day job. It details the story of Phil Knight (the founder of Nike) and it's not the story you think it would be. Phil's adventurous spirit will show you how and why he was able to build one of the world's most recognizable brands. From Phil's trip around the world, to his "grow or die" mentality, you'll want to be reading this book outside just incase you launch like a rocket.
