I am still a rank amateur, but years ago, I used to teach vocational classes at our local community college. The idea that we can be "perfect" with everything we do -- just replace that with "I am seeking excellence" -- that means that you have done your very best -- at the time --- you will always improve as you grow in your talents, but the most we can hope for is "excellence" not perfection.
Enough of my philosophy!
