I feel I wasted my money and time reading the first 59 pages of this book. Simon Sinek seems to be a person who has read and seen many YouTube videos and documentaries about brain and dopamine and cliche examples which he just used anecdotally to prove his theory. The first 59 pages are just about why apple is successful. Maybe he is right but the logic he gives can be applied to thousands of other companies which have failed in the past as well. Not recommended and stop following this guy but follow huberman on YouTube.
