Another pinner said-"My pediatrician told me about this years ago! It really does work. Magic Mouthwash: Remedy for Sore Throats and Mouth Sores. This seriously is a miracle for even the worst cankers. My kids love it."
I like this idea. Start the year with an empty jar and fill it with notes about good things that happen. Then, on New Years Eve, empty it and see what awesome stuff happened that year. Good way to keep things in perspective.
