Perhaps one day I will be beaten down enough to let it all go: My love, my ideas, my inspiration. Every inch of it. Maybe then I'll be seen as "brilliant" too.
The light at the end of the tunnel will appear when your ears take over. Believe me they will and you will be far more critical of your playing than any teacher. Record everything you do, in practice or performance.
The best teacher I ever had, AND I think the one who most improved my playing, was one who respected me enough not to touch my vision of the piece. He would simply help me with technical hurdles, give me his own macro views of the piece (not try to make me change 100 details), and perhaps remark that he found certain passages "convincing" or "not convincing". Other than that, it was up to me. He also gave my confidence a desperately needed boost. I wish I had had the opportunity to work with him longer than I did.
