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.
I'm not sure if this is the correct channel, but I've found www.daily-seven.com to be a helpful channel in getting myself to follow through with my habits or goals (or even getting myself to write goals/habits to begin with). Basically, it's an upgraded alarm clock: you tell somebody what you want to accomplish, and then have them call to remind you to do it. There's something about the added social pressure that makes a tremendous difference, even if it seems silly and self-manufactured.
