What's your personal take on habit formation?

I. E what are some non obvious tricks and connections have you made on your own journey to form and maintain good habits?

I like James Clear's idea of "habit stacking" from his book Atomic Habits. For example, every time you brush your teeth - clean the bathroom/sink real quick. Then, you're ensuring every time you brush your teeth (which should be at least once a day), you're getting the bathroom clean as well.
