A real estate guy from the US, John T. Reed wrote a review on various investment gurus which some he recommends but the rest he doesn't recommend. Robert T. Kiyosaki is on of his bottom list of gurus. An excerpt from his website:
I was told I would like this guy. His book was #1 on the Business Week best seller list. Eager to find another guy to recommend, I bought his book Rich Dad, Poor Dad in a bookstore and read it.
I recommend you guys read stuff on his website. But don't forget to put your thinking hats and filter the advises that you will get from other people. Dangerous advises can lead damage to your life.
