One useful thing is to start with the tinyest habit possible, and not worry about optimality for the habit forming period.
Yup. The Tiny Habits program I linked in the post is built around this approach. 2 seconds rather than 2 minutes, but same idea.
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.
