I always get myself to do things I don't want to by thinking "Future-me is going to be much happier when he finds that present-me did this already."
Helps me find the motivation to exercise, make myself a good cup of coffee instead of a kcup, do the dishes after dinner, lots of things. And past me is such a bro, saved me from present-me having to do those things.
Got back from the theatre about 10m ago, and I see why! It was a lot of fun, and while it did have some serious things, it also didn't take it's humorous parts seriously. For 2 hours and the cost of a ticket, I'd definitely recommend it.
