Cutting toxic people out.

Graduate software dev here.

At work we learned the boy scout rule: Leave the camp grounds cleaner than you found it. It's an analogy for software dev where if you're working on a file, find a way to make it cleaner than when you started using it.

At home I've started cleaning at least one thing from messy part of the house as I walk past it. One tiny thing is easy enough to do, and over time the results show.

Fighting back. Nobody crosses my boundaries from here on out.

Not exactly super small, but the return vs time spent ratio is massive. I have never had one and I got a dog. She is the happiest part of most of my days.
