29 - Whoever is trying to learn without taking lessons (sorry, I think so)
I'm sorry, but I have to take exception to this one. Some of us can't afford to take lessons, or can't find the time. I work full time, have two young children, and have little extra money. Still, I'm up every morning at 4 am to practice, and I'm at the piano again after we've finally got our kids to sleep. I read everything I can about piano technique and classical music in general, I listen to every recording I can of the great pianists, I pay very close attention when I play to make sure I'm doing everything I can to play well and to learn from what I'm doing.
I'd LOVE to take lessons, but I'm just not able. And the two teachers I had when I was a teenager were terrible! They never talked about technique, not even fingerings.
