Run for your life. Seriously. You only get one. Every hour is an investment in your future — if it doesn't pay dividends, it is lost, you might as well burn it playing video games or lying in the park (which is probably more fun). Note that the least interesting dividends are money; the best are love, friendship, helping others, novel experiences, travel, fun, relaxation, learning.<p>Glory isn't real. The harshest lesson of success is that the "feeling" of success is extremely brief -- hours, days -- if you ever feel it at all. (Most don't. So they keep trying to hit higher and higher peaks in order to <i>feel something</i>, but the feeling comes from inside, not from outside, so no achievement will cause it to arise.)<p>If you are 20-something and you want a partner, or a family, you better work on that now. If you want to live life on your own terms, you better start on that now. If you want to live a healthy life… you can't waste time.<p>So many "young people" I know think that they have time. They're waiting for real life to happen. Well, you don't have time and real life is now. What's 20-something…? Then 30s. Then 40s. Then what? When's the good stuff going to happen? Never, if you wait for it.
