Rich Dad/Poor Dad is not my favorite, it just happens to be the first one, and so the one to tell all the people to start.

Unfair advantage was a really good book. It was about the time Robert came across the book (drat, brain won't remember title) about being a professional (in a world populated by half assed amateurs). It is the real crux about using the gifts you've got. Don't hamstring yourself.

I think my favorite is The Cashflow Quadrant, well its the one that affected me the most.
