I do not think that there is any other quality so essential to success of any kind as the quality of perseverance. It overcomes almost everything, even nature.
John D. Rockefeller
A hero is one who knows how to hang on for one minute longer.
Discipline is doing what needs to be done, even if you don’t want to.
You just can’t beat the person who never gives up.
Recipe for success: Study while others are sleeping; work while others are loafing; prepare while others are playing; and dream while others are wishing.
W. A. Ward
