From “The Human Condition: A User’s Manual,” by Arnold Kunst
When you went to Mozart for a piano lesson you sat and watched/listened. Do the same thing: put your pride in your pocket and get comfortable with sitting at the feet of the master. Get used to the fact that, even if you’re very good at what you do you're not at the top of every aspect of your field; somebody else is. Make it your business to learn from him/them.
