That's the reason they are called lessons, because they lessen from day to day. Pleasurable experiences are fine, but if you don't remember them, you get that pleasure only once, and you can't even be sure of that. We don't ordinarily think about learning from eating a meal, but learning from the meal is one reason we eat it. A more important reason, of course, is that we are hungry. Roger C. Schank.
Experience comes from bad judgement.
Jim Horning The wind and the waves are always on the side of the ablest navigators. When a person with experience meets a person with money, the person with experience will get the money. And the person with the money will get some experience. If you take all the experience and judgment of men over fifty out of the world, there wouldn't be enough left to run it. Henry Ford A gem is not polished without rubbing, nor a man made perfect without trials.
