After Aaron and I decided to dive head first into this journey of simplification and downsizing, I found this video of Graham Hill talking about how less stuff CAN lead to more happiness:
Graham Hill founded the eco-blog and vlog TreeHugger.com, to help, as he says, "push sustainability into the mainstream," with a design-forward style and international, wide-ranging team committed to transforming complex issues into everyday concepts. (Bio taken from http://www.ted.com/speakers/graham_hill.html).
I get excited when I see that others are currently living the life Aaron and I want for ourselves and our future family...and they're doing it in MUCH less than 1200 square-feet of space.
