This is part of my new therapist's assignments for me, but I can't ever remember to do it. Currently I have the choice to use emoods or a chart for a whole month. I live with a wife and two kids and don't really want my emotions out in front of everyone so I'm leaning towards the app. It's just the remembering and being a better judge of myself. Everyone else loves to give me their input (read: wife) and tell me when I'm wrong.
