Here is one of my favorite quotes, from the man himself, Robert Collier, about our subconscious mind works. This comes from his book set "The Life Magnet" (which you can find inside of 'Secrets Of Success'.) ======
According to the English psychologist, Graham Dallas, a new thought or idea passes through four definite phases.
1st - Preparation. You have a problem to solve. You study everything relating to it that you can. You fill your mind with all the facts pertaining to the problem.
2nd - Incubation. You let go of the problem with your conscious mind. You pass it along to your subconscious and forget it—secure in the knowledge that the subconscious is weighing every phase of it carefully. Meantime you go on about your everyday affairs, attending to those ordinary duties which the conscious mind is capable of taking care of unaided.
3rd - Illumination. Those who do not understand the processes of the mind tell you of the wonderful idea that suddenly dawns upon them, solving the problem they have been working over for hours or days or weeks. What actually happens is that their subconscious has weighed all the facts, come to its conclusion and passed that conclusion back to the conscious mind.
Spurred on by confident faith upon the part of the conscious mind, there is no question the subconscious cannot solve in this way. But so many of us make a correct solution impossible by interrupting the deliberations every few minutes with worry and fear, or by telling ourselves that we cannot solve the problem. Of course, when you tell the subconscious that, it doesn't bother about the problem further. It accepts your judgment that it cannot be solved, and goes on to something else.
4th - Verification. When the conscious mind receives the conclusion ( the good idea) from the subconscious, it analyzes it in the light of all the facts it has, to see if the answer is correct. It tests it.
Perhaps the answer is negative, because of the fear and worry of the conscious mind. In that case, the problem must be sent back to the subconscious with the confident assurance that there is a solution, that the subconscious HAS it and can speedily find it.
Perhaps the answer is incomplete, solving only one phase of the problem. Refresh your mind again with every angle and send it back for further developing.
Don't talk about a new idea too soon. Let it ferment until it is complete, until it becomes so strong it pops out of itself— full born and perfect. Steam has little power as long as it escapes freely from the spout of a kettle. But stop up the spout, and it will presently blow off the lid!
Thoughts have little power as long as they escape through your mouth as fast as they are formed. You must dam them up for a while, set them some definite task to do, before they generate real power.
The trouble with many people is that they do not appreciate the difference between remembering and thinking. You give them a problem and they sit down, go through their brain files and look over everything connected with that problem they can find. If one of these files happens to contain a record of the solution of a similar problem, they use it. If not, they wait helplessly for someone to solve it for them. That is not thinking. That is merely passing your memory cells in kaleidoscopic review before your mental eyes.
Real thinking—connecting all these related items of information, and drawing logical conclusions from them, is something entirely different. It is like holding two pieces of electrically charged wire close to each other, and letting a spark spring between them. It is taking two memory cells, holding them before your mental eyes and connecting them with the spark of a related idea. Of course, that is an effort—probably the greatest effort there is—and many people are too mentally lazy to make such an effort.
