But one of the pieces of advice that I've held to closely over the years, find work that you love, runs against one of the basic assumptions behind the book - that work is something that is separate from the rest of your life, and something that should be avoided or limited as much as possible.
Michael Cage, in What I hate about the 4-hour work week, explores that thought even further. As Michael notes:
The world doesn't need any more people selling crap so they can live a playboy's life.
It needs people who are committed and passionate about who they are and what impact they want to be having. People for whom each day is an opportunity to do what they love, experience the ripples flowing from their efforts, and be well rewarded for it.
What is that thing that, if you were to choose to do it ... fully and without compromise ... would stir your soul?
Work can be difficult, it can be challenging, it can be frustrating sometimes. But if it's what you are passionate about, then those things don't matter.
