A strong, successful man is not the victim of his environment. He creates favorable conditions. His own inherent force and energy compel things to turn out as he desires.
Orison Swett Marden
We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light.
Plato
Give a man health and a course to steer; and he'll never stop to trouble about whether he's happy or not.
