"Thinking is a kind of living. To think and to be aware that we think is to be conscious; life without consciousness is but a shadow of life, having no meaning and being of no value to the individual. Our thoughts are the product of our thinking, and since these are of such vast importance to us it is imperative that we learn how to think rightly. I am not concerned here with that kind of profound cerebration known as “heavy thinking.” Few of us have the intellectual equipment to enable us, or the will power to compel us, to engage in such heroic mental exercise. I am dealing here with that kind of thinking done by every normal person every waking moment from birth to death. After all, it is not our heavy thinking that shapes our characters, but the quiet attention of the mind to the surrounding world day after day throughout our lives. Men are influenced more by their common, everyday thinking than by any rare intellectual feat such as writing a great poem or painting a famous picture. Feats of thinking may create reputation, but habits of thinking create character The incredible mental accomplishments of an Einstein, for instance, had almost nothing to do with the kind of human being he was; the constant, undramatic, moment-by-moment interplay of his mind with his environment, on the other hand, had almost everything to do with it. We all live in two environments, the one being the world around us, the other our thoughts about that world. The larger world cannot affect us directly; it must be mediated to us by our thoughts, and will be to us at last only what we allow it to be." - A.W. Tozer
