"Because he has a huge amount of previous experience in the topics he preaches. He backs them up with case studies, data and scientific evidence (especially the 4HBody)." What I see is a guy who got lucky once, in an industry rife with fraudulent or borderline-fraudulent claims and huge markups. I'm sure the oily guy in the infomercials selling "colon cleanse" quackery makes lots of money too. Now, because he lacks more meaningful entrepreneurial skills, he's leveraging that early experience into the self-help field, a field not known for a high barrier for entry, and where the customers are not particularly demanding. I just don't see any there there. In the universe of accomplishment, "sold snake oil supplements and self-help books amid rabid self-promotion" just doesn't amount to very much, as profitable as it may be for him.
