No man succeeds without faith. Whether you call it religious faith or label it something else. I don't feel anything worthwhile is accomplished without it. When you believe there is a Supreme Being guiding the destiny of this universe and that within each of us there is a little part of that Being, then you will have faith in yourself, in your country, in that Supreme Being, and in humanity itself.
