A better way to use this comparison is not as intimidation but as inspiration: "Somebody else has tried and failed, tried and failed until they succeeded, so I have a chance, too."
You may not be good enough to play very advanced music splendidly today but you are definitely good enough to be generous, persistent, and create art that matters to the people around you.
"I'm not good enough YET."
Big difference, isn't it?
