Started walking 10k steps a day after seeing myself in pictures and hating how I looked. I'd been fairly active in the past, but some injuries sidelined me. I found getting out and walking was much better for my mental health and creativity than staring at a screen. Embraced the zen of walking when it was cold or rainy out - I'm lucky to often see animals around me that I know most people near me are never seeing. Now instead of dreading exercise, I have the opposite problem of getting restless and pissy if I don't get my walking or biking in.
