Thus I came to believe I should, by no act of mine today, put forth any less than the best I have within me to give. I have striven, therefore, to foster this belief by study, thought, and action. In short, I believe the echoes of my past thinking, and doing, project themselves upon the sounding board of my present moment, creating visions for my life of tomorrow. This interaction of echo and vision determines what I am and do today. But this interaction must be practical for the moment, be it 1917, at the beginning of World War I when volunteer surgeons were needed in the Army Medical Corp; or again, practical for 1949, working with alcoholics and morphine addicts in each home community, its great problem of then and now.
