If you lost interest in the game, what did you do to develop interest in it again?

The only thing keeping me going is new content.
But my situation is a bit different because I am deliberately holding back on the progression of my sims until I get University.

I still haven't finished Strangerville yet, but what had me playing it was adding Mulder, Scully, and aliens into the story line.
I was having fun with that until I was distracted by reformatting rewriting one of my stories.
