I can't answer directly right now, but for feelings, here's food for thought. Yesterday I read a letter that a famous piano teacher wrote to the mother of an adult son who wanted to switch from law to music. The adult son had taken some lessons with this teacher. The teacher wrote quite cautiously about the young man:He seems to think that getting great technique is all there is to being a pianist - he has a wrong idea. Will he bother, day in day out, to slog out everything that needs to be done - or will he pop off mid-week to see his friends to impress them with his emotional fantasies, being fooled by their praise and encouragement? Will this young man bother to study theory and all the things that his own daughter had been trained in since early childhood? And does he know that pianist can't realy make a living unless he also teaches? In short, this teacher's letter was full of caution and doubt. The mother gave the letter to her son to read. The son moved to the city, and studied with the teacher.Oh, and the young man was the famous Schumann.
