I am totally a sucker for this kind of thing and even if I didn't like the idea, I'd love the name: Affirmacuff. Affirmacuff! An affirmation on a cuff on your wrist. The affirmations include 'Indulge yourself', 'Joy shared is doubled' and 'Carpe diem'. And apart from being affirming (affirmating?), they're really cute. They cost $40.50 each from FredLA.
