“In school we learn that mistakes are bad, and we are punished for making them. Yet, if you look at the way humans are designed to learn, we learn by making mistakes. We learn to walk by falling down. If we never fell down, we would never walk.”
― Robert T. Kiyosaki, Rich Dad, Poor Dad

Rich Dad Poor Dad is the story of Robert Kiyosaki's financial education. He had two 'dads' - one his real dad, who was poor, and the other, his best friend's dad, who was on his way to becoming a very rich man.
