I have to give this five stars just for the concept alone. It's a good fundamental truth that explains a lot of mysteries in the business world as well as life in general. It makes sense on so many levels and it's really, really, incredibly helpful for orienting you towards what is meaningful in life, staying aligned to your North star, and achieving long-term success instead of just short-term results. I'm really glad I read this book and I hope I continue to start with my why for the rest of my life. So in short, yes, I have drunk the kool-aid alllll the way. But I really do believe in this concept, from a philosophical perspective. If I'm not doing things that align with my passion, with my "why", with what matters most to me--then there's really no point in living at all. And I mean that quite literally. Being a walking zombie is even worse than being dead, it really is. So. This book is one of the most important things I've ever read.

The one thing I'll critique is that it's twice as long as it needs to be. It's repetitive. But that's forgivable.
