After studying the work of Robert Kiyosaki I'm suddenly questioning many of my traditional views. In short, he says that cash flow is the ultimate goal of financial success, not merely one's rate of saving. Saving a hundred percent of your income just means you've succeeded at being a hermit. He advocates investing in businesses rather than paper securities (401k etc). After all, what good is a pile of savings if you don't use it to make an impact on the world!?
