Every Spare Moment

I'm learning to discipline myself to write whenever I have a few minutes of time. I carry my little Moleskine notebook with me, usually in my back pocket, and when I have a few minutes to spare (like when I'm waiting in line at the bank or proctoring a test) out it comes. I generally try to jot down a few lines for whatever short story I'm working on at the time. The most difficult thing for me when I do this is getting my head back into the story, but I think it's getting easier with practice.
