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.
Welcome to the club. I've been at this since high school when I didn't want a car (much to the dismay of my parents) and didn't feel like bumming my friends for rides. Ever since then I've lived all over the US without getting behind a steering wheel once. It's harder in some places, but I'm lucky to live in an area with a long history and thus, more walkable layout. I haven't even seen a suburb in months.
I do recommend that you always have sunscreen and headphones, both of those will improve the quality of your day dramatically. I also would suggest that during summer you have some water with you.
