Nice summary of the Rich Dad ideas [Spanish]
To Spanish speakers, I recommend watching this recording of a seminar given by Ken McElroy in Colombia 2012 about real estate. It summarize pretty well the core concepts that Robert Kiyosaki explains in his Rich Dad books (such as Rich Dad, Poor Dad and Cashflow Quadrant).
I'm sure there are good equivalents in English, French or Dutch, but I haven't searched for them myself yet.
Do yourself a favor, and learn about these topics.
