A very long time ago, I bowled on the high school bowling team. The varsity bowlers were all better than me. I had a pretty consistent average of about 146. It varied little. I had never bowled a game of 200, and never seriously threatened to. Then I went to college, and one of the other guys in the dorm needed to know how to bowl for his required PE class. So I volunteered to teach him. You take so many steps, I told him. You swing the ball in a modest arc. You don't try to toss it really hard. You observe how the ball curves as a result of your delivery and then you adjust your aim points using the dots and arrows on the lane. You try to repeat your delivery exactly, so keep it as simple as you can. I was very patient as we alternated balls. He did pretty well for a first-time bowler. I think he scored almost 100. I began with six straight strikes, then missed my aim point by one whole arrow and ended with a spare. Then three more strikes. I bowled 256, and it could have been a lot better than that. When I joined the dorm's bowling team, my average for the whole season was about 185. When you try to teach something, your own knowledge and performance both improve. I found that true in Mathematics, as well -- to really learn something, teach it.
So, maybe by giving you pointers I'm actually being selfish. Sort of.
