The idea of this book is to uncover why you do what you do. This why is at the root of everything you do and if you know what the why is, you will be able to quickly tell if any action, idea, or opportunity “fits” your why. While this book is good, I would recommend the follow up (Finding Your Why) which guides you to your personal (or company) why.
Golden Nugget: If you know why you do something, then you can be more open to new, innovative ideas and make adjustments along the way. Whereas, if you are motivated only by what you do, you don’t have the underlying sense of purpose or desire. So when you run into roadblocks, the why will help you find a way around them.
