What's a knitter to do?

When she's at that point in her sock, where she knits and knits. Then knits some more but the damn thing just won't grow!
I could just knit some more and have faith that one day (hopefully soon) I'll be at the heel turn, or,

I could cast on for another project! It's my clapotis! Still in the beginning stages, but unlike the sock, I do feel like progress is being made! The sock will get another opportunity to grow as I head for some sunny weather (80 degree's here I come!) in Phoenix for a long weekend! Here's hoping I come back with a heel turn and a slight tan. Ok, at least a heel turn.
