We're talking about interpretation, so far as I can tell?
You're saying that:
The point is not to encourage people to live as fully as possible. It's a question he posits once you have already lived at least part of your life. It is not an outlook that determines future actions but a way to experience the moment. Nietzsche wants you to draw ecstasy from the moment, from the act, from the sheer fact of being alive.
I'll go with that, but
What you're doing, how you're doing it is irrelevant. Even if you've had a terrible, horrible life you should be prepared to do it all over again exactly the same way and draw joy and energy from the experience.
Yes, and no. Over to you, Freddy:
"What if some day or night, a demon were to steal after you in your loneliest loneliness, and say to you: "this life as you now live it, and have lived it, you will have to live once more and innumerable times more, and there will be nothing new in it, but every pain and every joy, and every thought and sigh, and everything unutterably small or great in your life will have to return to you, all in the same succession and sequence. Even this spider, and this moonlight between the trees, even this moment, and I myself. The eternal hourglass of existence is turned upside down, again and again, and you with it, speck of dust."
Would you not throw yourself down, and gnash you teeth and curse the demon who spoke thus? Or have you once experienced a tremendous moment, when you would have answered him: "You are a God, and I never have heard anything more devine".
If this thought gained possession of you, it would change you as you are, or perhaps crush you? "
The final sentence is the key one. Would the thought of an eternally recurring world change you, or crush you?
Hence, for me, it's about self-creation.
EDIT:
I know that this is not exactly how time in
Groundhog Day functions. Murray is able to change things, so it is not an exact representation of the mechanics of the eternal recurrence, but it does represent what Nietzsche was getting at. The point is that Murray, after going through despair and apparent meaninglessness, eventually embraces life.
I'm not saying Nietzsche should have got a credit or anything.
