Piglet nailed it. But let me say this. After over 50 years of exploring experimenting contemplation and conducting workshops all over the world I have seen over and over that true mastery is in the expression. And expression (the reason we are drawn to play music) can be mastered by a six year old in minutes. When you feel you are practicing too much it’s because you are not experiencing expression. If you think about you have had moments of soaring. That’s because you were not just playing notes, but “putting in expression.” It is so simple it’s silly. I hope that helps. - corky
