Go for a run

The best feeling in the world: meditation via running. All you need is a comfortable pair of runners and some music. Get into the zone. The zone I'm talking about is not a "diet" fad but an honest to goodness ZONE of awareness. It is a great time to get some thinking done, a great time to work out your problems without feeling overwhelmed. Not only that, you feel like you can breathe that much deeper once you've completed your run.
