You want to change bad habits, right? They say it takes 21 days to create a new habit or break an old one (it was Maxwell Maltz MD, actually, in his book Psychocybernetics).
I drafted a tiny little tool you could use, a habit changer chart, to help you in changing any habit towards something better. Just download it, print it out and fill it in!
You tick off a box each day you succeed (and a cross if you failed, but let’s not go there, eh?) Just name your vice in the top panel, stick it to the fridge door, and off you go!
