Quote from : The Practicing Mind: Bringing Discipline and Focus into Your Life Book

If you are not in control of your thoughts then you are not in control of yourself. Without self-control, you have no real power, regardless of whatever else you accomplish. If you are not aware of the thoughts that you are thinking in each moment, then you are the rider with no reins, with no power over where you are going. You cannot control what you are not aware of. Awareness must come first.
