"Up to a point a man's life is shaped by environment, heredity, and movements and changes in the world about him. Then there comes a time when it lies within his grasp to shape the clay of his life into the sort of thing he wishes to be. Only the weak blame parents, their race, their times, lack of good fortune, or the quirks of fate. Everyone has it within his power to say, 'This I am today; that I will be tomorrow.'"
-- Louis L'Amour
