Literally, Habits are double-edge sword it can rise you or it can fall you down so it's very sensitive to watch out your habits everyday and I think you will need to write it down in your note and you can make it with sign (+) if you see it helps you to get better in anything and it differs from person to person so may you can add sign to one habit and then you can write (-) to another and your friend do vice verse so if you do that everyday I think it will make your life more effective and will eliminate the life's bad habit as much as possible
