Courage is the first of human virtues because it makes all others possible.

[C]ourage is reckoned the greatest of all virtues; because, unless a man has that virtue, he has no security for preserving any other.

You will never do anything in this world without courage. It is the greatest quality of the mind next to honor.

Courage is a mean with regard to fear and confidence.

The ideal man bears the accidents of life with dignity and grace, making the best of circumstances."
— Aristotle

Quite often good things have hurtful consequences. There are instances of men who have been ruined by their money or killed by their courage.
