Nothing in this world can take the place of persistence . Talent will not : nothing is more common than unsuccessful men with talent . Genius will not ; unrewarded genius is almost a proverb . Education will not : the world is full of educated derelicts . Persistence and determination alone are omnipotent
Calvin Coolidge
You are not here merely to make a living . You are here in order to enable the world to live more amply , with greater vision , with a finer spirit of hope and achievement . You are here to enrich the world , and you impoverish yourself if you forget the errand
Woodrow Wilson
