Inertia

I've discovered that once I get to a point where something is completed (e.g., a chapter), I have real trouble getting myself to start the next part. At first it's like, "oh, I'll just take a little break and watch this movie/check out this website/whatever"... and then it's like "oh, before I start the next thing, I should really do some laundry/vacuum/pay the bills/update my thesis blog/etc."... and the next thing I know it's three days later and I haven't done a stitch of work. I wonder what that says about me....
