“What I’ve done,” will have to be good enough. “What I’ve left undone,” will have to be good enough too.
My statement is a variation on the hedonistic paradox. This technical proper name means that pleasant consequences are intrinsically good, that I’m motivated by what is pleasurable and the avoidance of pain, and that I’m not wholly satisfied by the pleasures my senses seek and perceive. So I accept what I have done satisfying my senses, but that, well, and this is the variation on the theme, if I’m honest, I really must accept what I’ve left undone, done poorly, and not done, and that, the pleasure I sought has past and is not found now.
My acceptance of the failure of my acts, i.e. accomplishments, is acceptance of my weakness.
