I play the piano and find that becoming holy is a lot easier than learning to play the piano well. In fact, it is easier than learning most other things. Let me explain. To learn to play the piano well, you must understand the piece you are playing, analyze its composition, and know how you wish to interpret it. Then it takes a lot of practice to learn all the notes. Even talented pianists spend up to 6 hours a day on practice. Some won't even play any work in public until they've mastered it for at least a year. You want to reach the point to be able to play the piece exactly the way you'd like to hear it played without any concern about the notes. As to becoming holy, you simply submit yourself to God. He then takes over and you place all your trust in him. The rest is up to the him, with no analyzing, no figuring out what to do, no memorization or any drudgery on your part.
