It is important that you learn how to control your breathing. Just paying attention to your breath is called meditating. When you control it by taking deeper breaths in, pausing, and exhaling slowly, you will learn that it can relax you. Doing this will also clear your mind. It will allow you to be in the present. You will have less anxiety, less depression, less fear. You will not be thinking of your past regrets or future fears. You will just be. Here and Now. Now is when action is the easiest.
