Concentration is my motto. First honesty, then industry, then concentration.
The man who acquires the ability to take full possession of his own mind may take possession of anything else to which he is justly entitled.
As I grow older, I pay less attention to what men say. I just watch what they do.
No man will make a great leader who wants to do it all himself, or to get all the credit for doing it.
One of the serious obstacles to the improvement of our race is indiscriminate charity.
Concentration is my motto - first honesty, then industry, then concentration.
