"The first constant factor is purpose. One must know that in whatever he does he is moving forward toward a goal. Aimlessness is the worst enemy of success. One can hardly feel successful in a bog. But as long as one has purpose he feels that his energies and creative thought are taking him somewhere, and there is satisfaction in the journey just as there is despair whenever we feel, as we often insightfully put it, that we are “getting nowhere.”"
