Robert Kiyosaki :
My poor dad said, "you need to know a lot about one specialty." My rich dad said, "you need to learn a little about a lot of things."
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.
