alright, i'll admit i have read a tony robbins book. about 4-5 years ago i read "awaken the giant within."
if you read his stuff, though, you shouldn't read it EXPECTING it to be a bunch of crap. if you watch a movie that you think you won't like, you just may make yourself not like it even if it's good. if you think of tony robbins as just some infomercial guy, you probably won't take him seriously. however, some of the stuff in his books is definitely true and can be used in positive way, imo.
