Something flipped in my head last year and I changed.
All my life, my thoughts darkened a little when I'd see litter. Who would do this to such a beautiful place? And sometimes it would lead me down a path of dwelling on other depressing human behavior.
I walk a lot when talking on the phone and in place of meetings in conference rooms. Now when I walk, I pick up stray trash and place it in the nearest trash can. I don't think about how it got there, don't care if anyone sees me do it, I only think about one less thing. It's a small but gratifying dopamine hit. It brightens my soul a little instead of darkening it.
The only thing is I have to tell whomever I'm walking with that I'm listening, I just habitually pick up trash. I wonder if they think I'm not concentrating on them.
