“Find a quiet space where you can be alone and focus on the dive ahead. Slow your heartbeat, establish a deep breathing rhythm, close your eyes or gaze out on to the ocean. Get yourself into a nice peaceful zone. Put away any thoughts circling around your mind concerning other aspects of your life, particularly areas where there is something negative going on. You are going diving; there is nothing you can do about anything that is happening in your surface existence while you are underwater.”
