Take advantage of your high energy day by getting a lot done. Get in some much-needed exercise while you're at it! Strap on a large backpack and walk to the organic grocery store to get your food for the week. Take extra canvas bags in case you need them for extras. Not only will you be preventing a few more plastic bags from hitting the landfill, as well as keeping your car in the driveway instead of wasting fuel, you'll also burn a few calories on your trek.
