Answer
This is a very tough question, and if you want a serious answer to it, I would recommend you read 'Zen and the Art of Motorcycle Maintenence' by Robert M. Pirsig.
This book changed my life for the better by teaching me the meaning of 'quality' and it sounds like you may benefit from it as well.
I know I have done a good job when I am satisfied I have given 100% effort to achieving the goal and am satified with the out come. I cannot give any more than my best effort, I will not give any less.
