Repositories are awesome, and we should have more of them.
I recently completed BJ Fogg's Tiny Habits, and it's a pretty lightweight way to install new habits (recommended). However, I realized I could use a better repository of useful habits.
So, please use this thread to suggest habits that you've found useful. Bonus points for evidence/anecdata of usefulness.
Obviously, 1 habit per comment makes upvotes a clearer signal of collective approval.
At the end of the day, go through the things you did. What did you do and why? How did you feel while you did it? Doing it in writing can be helpful (this is what journaling is). Or even get scientific and quantify things so you can analyze your data later!
cough this software I write for that last thing cough
