The Conscious Mind:
Our conscious mind is our logical, analytical side of our mind. It likes to look at things and analyze them. Our conscious mind is very weak but plays a vital role in our thought process. It is our critical filter, our sentry. It determines what will and will not go into our subconscious. It often doesn't do a very good job. It lets things in that it shouldn't and keeps out things that it should. It is very lazy about altering anything already stored; once a slot is filled it doesn't like to change it. Your conscious mind isn't very efficient but it is what we were given.
A good analogy is a computer. Your subconscious mind is like your hard drive. It is where all your information is stored. Your conscious mind is like your mouse, keyboard and monitor, it is how your hard drive relates to the world.
