Close your eyes and recall three things from your day for which you are grateful. They can be anything from the kindness and generosity of a friend to the bounty of a meal to the warmth of the sun to the beauty of a night sky. Try to be as specific as you can be in recalling what you are grateful for. Write these three things down in a journal. While you can do this exercise in your head, keeping a list of what you are grateful for has been shown to have many physical and emotional benefits over time. Each time you journal, try to write down three different things. Variation is the key to effective gratitude journaling.
