Practice is that inevitable "dues-paying" time that everyone must invest to pursue music. In the self study approach, the most difficult aspect of practice is the organization of musical and technical principles. Too often the player works in circles not really progressing, not knowing what to practice. Becoming aware of this lack of progress, he begins searching for sources of information. Books, recordings and other musicians are primary sources. Though these approaches are sometimes helpful, they are not flexible enough to solve specific problems for specific students. An individual can form habits from misinformation that can be detrimental to his progress for years.
Studying with a qualified teacher solves the organizational problems and provides a type of security for the student. Having dealt with so many self taught players and their problems, I encourage any serious players to find a qualified and creative teacher to assist their development. Every player is comfortable with and responds to varying programs of study but most can be helped by the right teacher. I do not deny the difficulty of finding this teacher but the effort required is usually worth it.
