"Do not turn the power of your mind upon others, but turn it upon yourself in such a way that it will make you stronger, more positive, more capable, and more efficient, and as you develop in this manner, success must come of itself. There is only one way by which you can influence others legitimately, and that is through the giving of instruction, but in that case, there is no desire to influence. You desire simply to impart knowledge and information, and you exercise a most desirable influence without desiring to do so."
