Paul Pollack's away message tonite is "if its worth doing, its worth doing badly." I think that's the quote that has the most different variants. I've heard just about every way of putting "not"s and "badly"s and "well"s into that sentence. I think if i were making a personality test it would include a question like:

Which of the following do you most agree with:
a) if its worth doing, its worth doing badly
b) if its not worth doing well, its not worth doing
c) if its worth doing, its worth doing well
d) there is no well, only do or not do
