I have a daughter who a couple of times a month will tell me that she want to quit piano. We have a number of friends who have told us that they regret quitting as a child. I relay this to her and work with her on her lesson. I have never played piano, but know enough about music from playing the trombone when I was a kid to be able to help. She gets past her quitting feeling, eventually, and when she reaches the end of the semester and has her recital, she is proud of her performance and that she persevered. Sometimes kids just need that push or need you to work with them to get through things.
