There are many truths in here, and as is the usual for Simon Sinek, it’s all very well written. There are 2 major flaws however that keep this book from deserving another star: 1) it’s way too long. 2) some of the explanations, especially on the neuroscience side, are shaky at best. He simplifies things to make a point, he makes assertions that should be opinions to make a point. It’s fine to do this in conversation, but not so much in a book that attempts to educate. It’s also not necessary: the points he’s making don’t need artifice to resonate.
