“Mind control is the result of self-discipline and habit. You either control your mind or it controls you. There is no half-way compromise. The most practical of all methods for controlling the mind is the habit of keeping it busy with a definite purpose, backed by a definite plan. Study the record of any man who achieves noteworthy success, and you will observe that he has control over his own mind, moreover, that he exercises that control and directs it toward the attainment of definite objectives. Without this control, success is not possible.”  –– Napoleon Hill, Think and Grow Rich
