In contrast with Christianity, where this life is to be "endured" for the promise of afterlife, "eternal return" is exactly the opposite - "enduring" this life is the worst possible decision, as you'll just have to "endure" it again and again for eternity. In context of "eternal return", good decisions are those that make life worth living for the sake of itself - embracing life completely and doing whatever you can to enhance your will to power (which Nietzsche sees as the source of all that which is good).
