Before you can change a bothering habit, or something you always react the same way on, the first step is to realize your habit and watch yourself how you act on it. Ones you have that realization and awareness of your habit, you have to catch yourself in the situation where your habit would come up and you should actively react differently. Do anything new! New thoughts, new reacting, new words to use. When you interrupt that habit and approach it from a new perspectives, your are able to break the habit. It takes at least 3 times of a different reaction on your habit to interrupt it. Become conscious about how you want to react different next time and act different. You can try different reaction and see which on feels the best. Play with it. To establish a new healthy habit it take time. Be patient and kind to yourself!
