Still another case. You may be more or less of an irritable nature--naturally, perhaps, provoked easily to anger. Some one says something or does something that you dislike, and your first impulse is to show resentment and possibly to give way to anger. In the degree that you allow this resentment to display itself, that you allow yourself to give way to anger, in that degree will it become easier to do the same thing when any cause, even a very slight cause, presents itself. It will, moreover, become continually harder for you to refrain from it, until resentment, anger, and possibly even hatred and revenge become characteristics of your nature, robbing it of its sunniness, its charm, and its brightness for all with whom you come in contact. If, however, the instant the impulse to resentment and anger arises, you check it _then and there_, and throw the mind on to some other object of thought, the power will gradually grow itself of doing this same thing more readily, more easily, as succeeding like causes present themselves, until by and by the time will come when there will be scarcely anything that can irritate you, and nothing that can impel you to anger; until by and by a matchless brightness and charm of nature and disposition will become habitually yours, a brightness and charm you would scarcely think possible to-day. And so we might take up case after case, characteristic after characteristic, habit after habit. The habit of fault-finding and its opposite are grown in identically the same way; the characteristic of jealousy and its opposite; the characteristic of fear and its opposite. In this same way we grow either love or hatred; in this way we come to take a gloomy, pessimistic view of life, which objectifies itself in a nature, a disposition of this type, or we grow that sunny, hopeful, cheerful, buoyant nature that brings with it so much joy and beauty and power for ourselves, as well as so much hope and inspiration and joy for all the world. There is nothing more true in connection with human life than that we grow into the likeness of those things we contemplate. Literally and scientifically and necessarily true is it that, "as a man thinketh in his heart, so _is_ he." The "is" part is his character. His character is the sum total of his habits. His habits have been formed by his conscious acts; but every conscious act is, as we have found, preceded by a thought. And so we have it--thought on the one hand, character, life, destiny on the other. And simple it becomes when we bear in mind that it is simply the thought of the present moment, and the next moment when it is upon us, and then the next, and so on through all time.
