I never compare to others. Only technically. Technically it is simple - you play all the etudes properly; he plays 2 of them. Etc...
Remmember the point in playing the piano is the music.
If you enjoy the music incredibly, then you are a great pianist. If you truly enjoy, your sound will improve, and your joy comes through to the audience. If you don't, but have technique, then you are a pianist, but not a musician, and I would not have you playing anywhere.
