It is never worth while to absolutely exhaust one's self or to take big chances unless for an adequate object. - Theodore Roosevelt

Each man should have all he earns, whether by brain or body; and the director, the great industrial leader, is one of the greatest of earners, and should have a proportional reward; but no man should live on the earnings of another, and there should not be too gross inequality between service and reward.

From the greatest to the smallest, happiness and usefulness are largely found in the same soul, and the joy of life is won in its deepest and truest sense only by those who have not shirked life's burdens.

...If there is not the war, you don't get the great general; if there is not the great occasion, you don't get the great statesman; if Lincoln had lived in times of peace, no one would know his name now.
