good – better – best
who concentrates on being better, needs to compare to some worse. No matter in which field: to be better can be achieved in two ways. Improve; or worsen what you compare against. If your goal is to be better, recognizing the good in your object of comparison threatens your success. Trying to be best expands this problem to every object of comparison.
My goal is to be good. Comparison is not necessary. Good can be better than best.
