My old man who was one materialistic SOB if there ever was one told me this: "Never ever do something just for the money; you'll hate it, hate yourself, and most likely fail." I don't know what you learn in any business course that tells you that the purpose of business is to make money. Bullshit. The purpose of any and all business is to solve problems and the second you forget this you lose your way and any justification for continuing life. Remember how our once great car business forgot that the purpose of a car was dependably and economically transporting our families from one place to another, quickly and mostly enjoyably. The Japanese did not suddenly just take over, they simply produced the cars that solved our problems. Think about it. What problem does FaceBook solve? It sure ain't getting all those Wall Street pricks rich.
