"Think of a wonderful thought," as Peter Pan would say, "any happy little thought...and you can fly!"
Take a moment to think of something that makes you feel really happy, maybe it's a special memory of a person or a time when you felt most complete. Relive how it felt, in your mind, in your body as it tingled through you, and in your spirit. Close your eyes and bask in the sensation. Breathe it through you, feel a smile spreading across your lips as the feeling takes hold; feel how it affects your heart, your midriff.
Feel happy today!
