Without a defined target the mind’s energy is wasted. You give your brain a clear picture to follow when you have identified your desired outcome. The brain needs this to be effective. When you know your outcome, you give your brain a clear picture of which kinds of information being received by the nervous system need high priority. You give it the clear messages it needs to be effective…. if it doesn’t have a defined target, the mind’s energy is squandered. (Robbins, Anthony. Unlimited Power, p. 200-201. NY: Fireside, 1986.)
