I would say the most satisfying thing actually is watching my three children each pick up on their own interests and work many more hours per week than most people that have jobs at trying to intelligently give away that money in fields that they particularly care about.
Whenever you are about to find fault with someone, ask yourself the following question: What fault of mine most nearly resembles the one I am about to criticize?
