I'm like Vicki, I use chocolate (limited to dark for my health, but still chocolate) and I put a picture of the one I'm making the quilt for up prominently in the room I work in. THAT insists I finish what I'm working on.
I have to fess up to doing many at once though, if it's a large item I work on several smaller ones for the breaks. I just can't keep my mind working on only one thing at a time.
Chin up, you'll work through this. Come here every day and we'll help encourage you! Promise!!!
Hugs,
Sharon
