Look in any bookshop at their Best Seller list today, and you'll see a mass of autobiographies of the rich and famous. From empire builders to glamour models to footballers, they all tell a different story, but each has a thread in common - they focused on the positives and overcame adversity.
That's the way of the world; life's achievers allow positive reasons why 'they can' to flood their consciousness, and drown out negative reasons why they can't.
For the student, this attitude to studying is paramount. To successfully complete a training program, the biggest tool in a trainee's workbox is a positive mindset. An optimistic approach brings about all sorts of possibilities, circumstances, answers and opportunities to achieve. By contrast, a negative outlook thwarts creativity and blocks our learning receptors.
This is because of our Reticular Activation System - a mechanism that automatically tells our brain what to focus on. Over our lives, we've experienced a huge number things that no longer remain in the forefront of our minds - the majority of what we've learned moves from our conscious mind to our sub-conscious mind, a kind of cupboard that stores all our past beliefs and knowledge.
When we consciously attempt to do something, our Reticular Activation System (RAS) will search the sub-conscious mind for any relevant information it holds, and bring it to our attention. If we're walking down a street, we're only made aware of things that have meaning to us - the rest is just background noise.
Therefore, if our conscious mind has generally been transferring positive, upbeat messages to our sub-conscious mind, then that's what it will send back. But if our sub-conscious has been fed a bunch of defeatist, downbeat messages, then equally that's also what will come back.
It appears that achievers can manipulate the messages going through to their sub-conscious minds by deliberately programming their RAS, and selecting the exact messages the conscious mind transfers. For achieving goals this makes it an essential tool, because the sub-conscious mind can't distinguish between real or imaginary events.
In other words, we need to create a very specific picture of our goal in our conscious mind. The RAS will then pass this on to our subconscious - which, as it believes everything it's told, will then help us achieve the goal. It does this by making us aware of all the relevant information which otherwise might have stayed as 'background noise'.
Napoleon Hill said that we can achieve any realistic goal if we keep on thinking of that goal, and stop thinking any negative thoughts about it. Of course, if we keep thinking that we can't achieve a goal, our subconscious will help us not to achieve it.
