Amor Fati
Nietzsche's formula for the affirmative attitude of saying yes to one's life as it is — including its suffering — and willing nothing to be otherwise.
Amor fati, Latin for love of fate, is Friedrich Nietzsche's formula for the affirmative attitude that he held to be the highest mark of philosophical health. He introduces the phrase in The Gay Science (1882): My formula for greatness in a human being is amor fati: that one wants nothing to be different, not forward, not backward, not in all eternity. Not merely bear what is necessary, still less conceal it — but love it.
The attitude is closely related to Nietzsche's doctrine of the eternal recurrence: the test of whether one truly affirms one's life is whether one would will to live this same life over and over for eternity. Amor fati is also Nietzsche's revaluation of the Stoic acceptance of fate: where the Stoics consent to what is necessary, Nietzsche insists on actively loving it. The concept has remained central to existentialist and post-existentialist appropriations of Nietzsche.
