There are many ways to think about our musical development. I've produced the following:
Level one, student: At level one the student learns to control their hands. i.e. the hands do what they are told. I'm told this takes about 10,000 hours. I believe it. This level is about technique, repertoire, ear training, theory studies, concert going, and practice, practice, practice. It is about following the teachers' directions, and maintaining and nourishing your personal curiosity, patience, and faith in the process.
Level two, professional: At level two you have professional hands that do what they are told. At this level you practice maintaining and refining your skills.
Level three, artist: At level three you have something interesting to say and the ability to communicate it. Artists blend this elevated level of creativity and skill into dazzling musical displays. How do you become an artist? I don't know. However, I do know you must go through the first two steps to reach level three. Too many folks try to skip all or part of the first two steps in their haste to be "artists." This is misguided, naïve, and foolish.
Get off the internet and go back to the practice room!

You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
