I used to do this, and I am going to do it again. I had a watch with about ten alarm settings, more than I needed, and I set one to go off at a certain time every day. When the alarm went off, as I reached my left hand to stop the right wristwatch from beeping, I would think of something to be grateful for. And I restricted myself to thinking of something new every day, because, as easy as it would be to just say "Oh I give thanks for Peggy for how she looks after me and does so much for me and us and my Mom, and always with a smile, too" but I could say that every day and the goal is to vary my gratitude.
Maybe I'll decide to do it every morning as I lumber outside to retrieve the Sunpaper from wherever it wound up. I feel good when I do this, and I don't know why I stopped.
Will you join me? It's simple - it's low-calorie, non-fat, slightly addictive, carries with it no unpleasant side effects, but plenty of pleasant ones.
Here's the one I'm going to start with: "I'm grateful that I am even here to give thanks!"
