Anyone attended Adam khoo's wealth academy courses? Worth the course fees?

Adam Khoo is one of the many self proclaimed gurus who claim they can make you rich by buying their courses. This has become a hackneyed expression now but still applies. If they're making so much money, why bother to sell courses? Can you see Warren Buffett selling courses? They make their money from selling useless courses to victims like us. I am telling you all this so that you won't have to go through what I went through with Adam Khoo. Don't believe me? Buy any of his courses and learn it the hard way.

There is no need to attend the course. There's a lot of good materials online (Seedly).
