My ex owned the last car I drove. She did not have a license, so I was pretty much the only person to ever drive in the house. Now I'm out of her house, so no more car. I'm walking everywhere in an extremely car dependant area, there's public transport it just sucks ass. However, I'm liking the walking. The more I do it, the less I even think about it. My ass is gonna look great, I can still get pretty much everything I care about within walking distance, life is good.
I'm really happy that you're making it work! Consider buying some orthotic insoles if you can spare the money, I bought some on a lark and didn't notice how often I was in minor pain because my shoes were not adequately supportive.
