I agree about the inspirational part. But if that is the case he should be selling his services as motivational speaker and not trading mentor. As long as he labels himself correctly, everything is fine.... The cups and T-shirts are probably for PR, it is basicly free advertisement. He can get newbies who saw someone at a barbecue in a Jelly T-shirt, stroke up a conversation and eventually ended up a paying costumer. As you said, he is a pretty smart entrepreneur....
You got good points, no argument here. To each, there own. Other books from great traders: Soros, Lewis Borsellino, Marty Schwartz. Ed Seykota (pamphlet),etc. I think at a certain point they think about legacy and what they will leave behind. Soros, Borsellino didnt write thier books in thier 20s or 30s but once they were established nicely. They wrote them in thier 50s-60s, pretty much around Millers age. EF
