On perfectionistic suffering
Splitting what is into good/bad, perfect/imperfect, proper/improper, success/failure, and so on creates false dichotomies. A false dichotomy produces a perception of alternatives to what is. A belief that the reality does not have to be what it is at any given moment leads to a desire for it to be what it is not. Constant rejection of what is and a desire for what is not is the essence of perfectionistic suffering.
