You are enjoying something, and suddenly a thought comes flying out from your deep subconcious that causes you doubt, guilt, fear or anxiety. For example, you are taking a nice hot shower and enjoying it. Suddenly a thought comes through telling you that you should not waste hot water. Consider that thought, assess whether it is valid, and if not, let that thought pass, and continue to enjoy the shower. Don't jump every time your subconcious mind comes up with an objection to something that you enjoy.
