I used to keep a diary, but I stopped since it took alot out of my day. In stead I usually email my friend in Duke about how things are going in my life, and he replies back..kinda like an interactive diary. I don't think it would be that difficult to write down your automatic thoughts, but I guess it would all depend on whether or not you were willing to do them, since they might find it a little tedious. And like Angela stated, if I were in therapy, that would be enough reason to start a journal.
