A new hobby doesn't require a ton of investment, either. Often you can go onto Freecycle or Craig's List and find just what you're looking for. You can also post a "Wanted" ad if you don't see what you're looking for. I have had nothing but good luck getting rid of things I no longer needed (and getting things I did) using both resources. Positive experiences on both sites also reinforce my sense that the world is a pretty cool place, and that the more connections we make with each other the better and better it gets.
Conclude your week with the Downshifting Pledge; you might even hang it up somewhere to remind you to live your life deliberately, each and every day:
"I hereby pledge to slow my life down a gear for the benefit of my health, my well being, my environment and for those around me whom I dearly love."
