From Superman & Batman Generations, a little Silver Age-ish Superman.

[neverendingbattle]

When I left Earth, I did so to find the places, problems and especially the people that need Superman. I don't see any reason to change that goal now, so I won't disapprove of you choice to bring me into the fold, so to speak. After all, I've been Superman for over ninety years now. There's no reason to stop no matter where I go.

And finding those problems, places and people I mentioned has never been too hard, so I why don't we try some? We can start small if you're feeling daunted.
