Managing your mind should be one of your top priorities. Your mind is like a computer, it only spits out the data you feed it. Winners work hard at investing the right material inside themselves. Dr. Hans Selye researched and popularized a tiny membrane in the back of our head known as the RAS: Reticular Activating System. Your RAS has a primary function: it moves you in the direction of your dominant thought at that moment. We naturally act on what fills our minds.
