Imagine you were stuck in The Vatican for the rest of your life what would you do?

Go through their immense archives and collections. You'd need multiple lifetimes to get through it all.

Stuck how?

There are no border checks between the Vatican and Italy.

Spend forever staring at (maybe even touch) the art.

And

Investigate if they really do have an assassin group.

Well, fortunately, I already know Latin.

Well I'm about to be a pain in their asses on the topic of queer liberation.

Read all the books in the secret library.

Probably hang out with Father Robert and the Vaticats

Focus on my pasta cooking skills and take them to a legendary level.

Open a brothel.

Hang all the pedos. There'll be a lot of swinging dicks.

I fail to see the difficulty in this.
