While going for a walk or biking back from work, if I have time and it's not raining, then I like to clean as I go [1]. Picking up and throwing away litter that I see on the street. Sometimes that might involve trespassing, but it's for the greater good.
Like you, I started logging my expenses too! And I still do that. I'm using some scripts on my phone, with one icon on the homescreen for each kind of expense, logging to a TSV.
It has made me more self-conscious about spending money, but that's probably a good thing! Pressuring me to give more money to beggars and spend less on bubble tea.
[1] UncleBob applied "clean as you go" to code, too https://www.youtube.com/watch?v=BSaAMQVq01E&t=2021s
