Read Thus Spake Zarathustra. The question is, would you do it again? If you would, it's a good life.

And I don't believe the eternal recurrence relied in identity, but rather simulicrum. This aligns with nietzsche's views of seasons or types or other things that recur, "its summer again, but not the same one as every other summer" "there are three crows right there, but not the same crow."

I also think the recurrence had a suggestion that perhaps it could be driven by will. I can't recall if it was in that book itself or will to power, but I recall a section on the consciousness of atoms and predictability not being evidence they were not. Thus, to look at the recurrence as merely a manifestation of physical order that is not driven by consciousness and will may miss something fundamental.
