Well considering his business is motivating people to get into business...I'd say his business is pretty successful. Everyone who fell for it and coughed up huge amounts of cash for just your average motivational course, not so much. He's like an inferior local version of Robert Kiyosaki.

RK is dubious as hell. There's like almost no records of his claims, and his main business is selling you on ideas that you think are backed by personal experience. He got rich from motivational books and courses, not from his so called "real estate" business. His books are fun to read though. There's no denying that he's a darn good motivator and that he writes great stuff (along with collaborative efforts with industry greats such as Donald Trump).
