Which is more worthwhile earning: a large fortune or the esteem and gratitude of the nation? This question is prompted anew by the death of ex-Secretary of the Interior [Franklin K.] Lane.

Frank W. Woolworth once told me that the turning-point in his career did not come until he was thrown flat on his back by illness. He was sure that his business would go to pieces during his long, enforced absence.

After that Woolworth left many problems and difficulties to be solved by subordinates and turned his attention to big things.
