I think it means you don't want to do whatever it is you're working on. Sometimes I tell myself I'm going to have a whole day of sewing, and then spend the morning on the computer, wasting precious sewing hours. I think it comes down to whether I want to sew or not. If I haven't sewn for a few days, I can't wait to get to the machine and nothing gets in my way. If I've been sewing a lot, I'm much more distracted.
