Think about a player or sound you like. When you play you must get brain activated. When you play you use motor functions not senses. You must allow mistakes. Prepare sound in the head.
Flow is greater playing than singing.
Exaggerate to separate shades of gray into black and white. When you let go of a habit you must replace it with a new one. Fight or Flight - if you miss a note ignore what is wrong and concentrate on what you want to hear. We don't play by phrases-we create phrases. Building phrase by individual notes.
