Trying to remember that no one notices

I know all about the missed notes and the fumbling fingers,
the high notes that cracked and losing the beat, eventually
finding it.
No else noticed.
I'm in my head judging my performance for rhythm, intonation,
fluidity, color, tone, energy and musicality.
They probably don't notice any particular thing except
that I am playing my heart out
in spite of the missed notes and fumbling fingers.
They could only be touched.
