Observation: Your teacher sees many things you can't. He/she sees you move in real time, and from multiple angles. Even if you're in front of a mirror, you still don't see it. Believe what he/she says, even if how you're doing it feels right and you don't see the flaw in the mirror. Make the adjustments he/she tells you. That is why you chose him/her as your teacher, after all.
