Getting git to help my memory

I have a somewhat unusual question. I often forget to push after committing,
and a few times this has come back to bite me. (One time I didn't even really
realize for a couple months because I was working on other stuff, so
unraveling the conflicts was "fun".)

Is there a way I can get git to print a "don't forget to push!" reminder
after it commits?

The best way I can think of is to put a post-commit hook in there. I haven't
tried it but I'd assume it would work, but would have to be on a
per-repository basis instead of global.

(I use git mostly for just my own projects, and almost always mostly in sort
of a centralized setup: I've got one bare *the* repository that I clone, and
push to and pull from that rather than between the copies. For a variety of
reasons, I'm pretty sure that model wouldn't work super well for me.)

Thanks,
Evan
