The course of human life involves so many disappointments, so many failures, so many heart-aches, that no one can avoid doubting. There is a peasant saying, "He who has once burned his tongue with hot milk tries to cool even buttermilk by blowing on it." When a man has been deceived by one person, he distrusts ten people; when he has found one person unreliable, he may perhaps consider a hundred others to be so too. After failing in one thing he suspects he will fail in a thousand things. So many things take away that natural and powerful quality which was at first present, that faith which is the secret of the whole creation, the secret of all success that can ever be attained in life. This faith is broken by life's discouraging experiences. When confidence in others is lost, then confidence in self is lost also; and the more it is lost, the more failures one meets. A doubting person considers himself to be wise and one of simple faith to be a fool. Whoever he sees he suspects; whatever he hears he questions whether it be right or wrong. He will doubt even his friend in business, waiting for the time to come when he can trust him. But that time never comes. His very doubts create doubts in the mind of the suspected person; and often the doubts come true as the effect of the doubter's thought; or at least it creates an illusion which for the moment shows the picture of his doubts.
