To get through this you are going to need to read a hundred or so pages of why Zappos is such an amazing company how how they are changing the world. That said Tony does make some interesting points throughout the book. His story of how he got started in the tech industry first with Linkshare and then with Zappos is quite an interesting read.
Profits > Passion > Purpose
This is the main concept of the book. You start at the bottom of “Maslows hierarchy of business” in search of profits. Once you have that covered you are more motivated by doing things you are passionate about. When the enthusiasm for that dies off you need to find your businesses purpose. This ties in with your personal search for happiness too which can be closely related.
It’s an interesting concept and a good read for the most part. Just flick through all the employee emails he seems to have bulked the book out with.
