Ok I can't resist my little anecdote. I've been playing racquetball for 
8 years and now play with people on campus, but I lost a lot in the 
beginning because apparently I sucked! The coach showed me what I was 
doing wrong in about 5 minutes and after a few weeks of practice I'm now 
at a reasonable skill level, orders of magnitude better than I was 
before. Its obvious in retrospect what I was doing wrong before but I 
didn't have the insights to improve myself on my own.
