Anything he wants? There is a whole universe of things to do. So many books to read, so much music to listen to, so many things to learn and build and understand.
I just can't imagine being bored, not in a million lifetimes.
What about a million and one?
Ahum, no civilization: no books, no music, no building.
No, just no new books. Still plenty already written for a few hundred lifetimes' worth of reading, though.
Reminds me a little of "The Last Answer" by Asimov...
