I took exercise this morning! I was quite surprised. I was lying in bed about half an hour before I needed to get up, and thinking wouldn't it be nice if I had enough willpower to get up and go for a run before work every morning like I used to when I was doing summer jobs, and suddenly it occurred to me that if there was no way I was getting back to sleep anyway then I might as well actually get up and do so. So I did. I wonder if I can keep it up.
