This is what I do. I grab my camera (which is an iPod Touch these days) and head out for a walk in the woods... there is nothing like the fresh air and boost of oxygen you get walking through a coniferous forest. I take as many photos as possible and then come back, post a photo and talk about it. If the river is calm I will also head out in the kayak and take pictures of flora and fauna, turtles and autumn color. A good 2-3 hours outdoors and I am recharged and ready to go .... That's what I do.
