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.
This is how I would train a pigeon to compulsively throw dice like crazy - Burrus F Skinner.
I don't think this will be good to you in the long run.
I forgot to mention in the post itself. I only allow myself one roll a day, so I have to decide if I want to take the chance on something for a snack in the morning, or with lunch, or later on in the evening. I can't train myself to throw dice like crazy because only the first one for a day counts.
