A healthy (and inspiring) goal for 2007: Embrace daydreaming. Harnessing the power of visual imagination is an efficient and enjoyable way to activate the relaxation response. Try picturing a place from your past, where you felt happy, secure, and peaceful.  Then imagine yourself there, making all the sensory impressions – smells, sounds, sights – as sharp as possible. Daydreaming is a simple, cost-effective way to feel happier and calmer in no time!
