Did Robert Kiyosaki (author of Rich dad Poor dad) just rob me of $40?

[Robert]

I'm eager to learn about the world of bussiness and investing and am only 16 so I decided to get his books. I read his book Rich dad Poor dad and was interested in his ideas. But after reading the sequel (Cashflow quadrant) and this review http://www.johntreed.com/Kiyosaki.html
I think that I just got robbed. The books don't seem to offer me any real advice and everything is extremely repetive! It only refers to the same things over and over again, while telling his life and stories of success.

SO I really want to know what other ppl think about Kiyosaki.
