Depends on what it is. Am I good enough to participate in the Nathans Hot Dog Eating Contest and have a chance at winning? Nope. Good enough is a state of mind one must justify to his or herself. My mind is not capable of any rationalization that my stomach is large enough to consume over 70 hot dogs in 10 minutes! Now to eat 5 in 10 minutes oh yeah baby!! Love those things.
Good enough is never enough. The relentless pursuit of perfection drives/consumes some people almost to a fault. I am one of Those people but it has its advantages in some things Not hot dog eating though.
