Every concert pianist knows that the surest way to ruin a performance is to be aware of what the fingers are doing. Every dancer and acrobat knows enough to let the mind go, let the body run itself.

You are all sleepwalkers, whether climbing creative peaks or slogging through some mundane routine for the thousandth time. You are all sleepwalkers.
