I've suddenly got a lot of people asking me to do things and I am very much out of the habit. It's not hard to say 'No' but most of these things are things I'm not averse to. My calendar is rapidly filling up and I'm getting a real sense of anxiety.
I think I don't like committing to stuff, and I used to commit to stuff all the time. The hardest thing is that the thing I hate more than committing to stuff is cancelling commitments. Perhaps I wouldn't be so anxious if I knew I could happily cancel without letting myself down.
