There's a pretty wide spectrum between 4 hours per week and working yourself to death. As a co-founder/technical person, I immensely enjoy what I do. Frankly, I'll get bored pretty quickly sitting at the beach and staring at the ocean. It's fun and relaxing, but I kinda "get the point" after some time. Whereas, there are endless challenges to keep me motivated, curious, and ultimately satisfied "at work". It was more or less the same satisfaction and fulfillment I had as an employee. I just enjoyed the challenges and still got compensated generously back then. Disclaimer: I didn't read the book. I'm sure it has some great points or it won't resonate with so many people. Also I should mention that at our company we instated a 45-days holidays per year policy (this includes personal and public holidays, we're 100% remote, no VC, but no dreams of mega money). So we do see a lot of value in not working to death.
