After college I worked for fifteen years averaging roughly 75 hours a week and then retired. I did it to buy back the last half of my life.

What money can do that's important is not buy cars, boats, houses etc. It is that it can buy you something far more rare. TIME! Time to spend with loved ones, time to read, time to stay in shape, time to go to the beach, time to travel, tim e to study, time to help others etc. In short time to do whatever you wish.
