I keep having to take time off for health reasons, and then I sometimes find that I've lost the impetus to quilt. What I'm doing right now is to keep the quilt I'm working on by the bed (I spend most of my day in the bedroom; go for whatever room works for you) and tell myself that I'm just going to quilt a few stitches. I usually end up doing more than that, but even if it's just a few stitches, at least it means I've picked up a needle that day.
