When you sit down and play piano, how do you evaluate how you've played?
Are you "never good enough?"
Do you get frustrated when you play a wrong note?
Do you like it if it "feels good?"
Are you satisfied if you've expressed something emotionally?
Does the audience's response matter to you?
Do you try to play in a certain way, and feel like you've missed the mark if you don't succeed?
Are you mostly aiming to have fun and enjoy the process of playing piano?
Which of above responses, or others, matter to you the most? Choose wisely, because your musical health depends upon it.
