DOUGLAS MACARTHUR - General of the Army

"Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them;While the sun, or the light, or the moon, or the stars, be not darkened, nor the clouds return after the rain." 

Ecclesiastes 21:1,2

People grow old only by deserting their ideals. Years may wrinkle the skin, but to give upon interest wrinkles the soul . . . You are as young as your faith, as old as your doubt, as young as your self-confidence, as old as your fear, as young as your hope, as old as your despair. In the central place of every heart there is a recording chamber, so long as it receives messages of beauty, hope, cheer, and courage's long are we young.
