That is a very advanced question for a young person to be asking. Perhaps you are more ambitious than I. I am 44, and had no idea what my life would be like. I had no obvious plans in life, and still don't, nothing grand, anyway. I did buy a Mercedes 500 SL recently. I never thought that I would ever own such an expensive car, and now I have one. I thought I would be rich and retired by now, and I am neither. More cranky than ever before, get more easily riled when things don't go my way, have less patience with other people than ever before, but generally things are looking pretty good. Body is fading, I don't get as horny as often, but I don't really care, either. You are too young to be concerned about these things. Enjoy, cause we don't have that long to go, in case you haven't noticed.
