Who decides that it's not good enough?
Who decides that your pedal part was with mistakes?
Who decides that you need to repeat this voice combination 5 more times?
Who decides that you mixed up the manuals?
Who decides that your touch was too short or too long?
This person, of course, is you.
When you realize this, when you understand that there's no one who can choose or decide for you, suddenly the great weight of responsibility is upon you.
This responsibility is also a liberation, though. A freedom to achieve perfection of whatever level you choose.
The only question that remains is this: how bad do you want it?
