I make the superabundance of plot bunnies work for me: there's always a point where I get bored with the thing I'm working on/decide it's awful and terrible and a no-good idea/can't figure out what happens next. So I put it down and rotate to a different fic. Rinse, lather, repeat, and eventually I come unstuck or realize that no, the fic is good after all, and can move forward again.
