A common complaint is that women's clothing is very bad for pockets. Over the past couple of months I've attended two parties in drag, and this is by far the strongest sympathy I've developed from the experience.
I am a man and my mother always told me not to stuff my pants pockets full becasue it makes me look fatter: wider hips. Her recommended solution was, somewhat ironically, a cowboyish man-purse. That may be the reason: women may care more about not looking fatter than men.
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.
