If you happen to be one of the fretful minority who can do creative work, never force an idea; you'll abort it if you do. Be patient and you'll give birth to it when the time is ripe. Learn to wait.
Robert A. HeinleinAt least once every human should have to run for his life, to teach him that milk does not come from supermarkets, that safety does not come from policemen, that 'news' is not something that happens to other people. He might learn how his ancestors lived and that he himself is no different--in the crunch his life depends on his agility, alertness, and personal resourcefulness.
