It does not. The entire book is about how he cleverly figured out how to take his struggling small business and automate, streamline, or outsource all its parts until he only had to actually attend to it ... roughly four hours a week. The rest of the book that isn't about this is about how to use your new-found free time to live an enviable life, using himself as an example.

I say again that I am a fan of his and that The Four Hour Workweek had a lasting positive effect on how I think about work and how I think about the value of my free time. I am not saying that the content of his books is bunk because he is an aggressive self-promoter. I am rather saying that the content of his books is in a sense inextricable from the fact that he is an aggressive self-promoter, perhaps because a hidden theme across all his work is that being an aggressive self-promoter is useful.

ETA: He also uses other people as examples, in all his books, but he always includes himself and his personal anecdotes. I wanted to clarify that the books aren't actually 100% about him, they're not even 10% about him, but his signature and his exploits run throughout them.
