Nearly all men can stand adversity, but if you want to test a man's character, give him power.
White House
…That this nation, under God, shall have a new birth of freedom.
…And that government of the people, by the people, for the people, shall not perish from the Earth.
In the end, it's not the years in your life that count. It's the life in your years.
Character is the virtue of hard times.
It is difficulties that show what men are.
Occasions of adversity best discover how great virtue or strength each one hath. For occasions do not make a man frail, but they show what he is.
