I know about the disappointment of being a mediocre musician. When I was 13 or 14 years old, I first heard the 3rd movement of the Moonlight Sonata. And I determined that someday I would be able to play it. Of course, it's a virtuoso piece. A few years ago, I decided to give it a try, even though it was beyond my skill level. Even, though, ideally you should possess the required skill level for a piece, I thought, "Why couldn't I use the process of learning the piece to acquire the necessary skill?" I worked on that piece for years. Some people even thought it was good. More perceptive listeners said, "You know, it's not bad." But it took years to get to "not bad." So I decided to content myself with learning easier pieces that I could learn to play really well.
