We are prone to judge success by the index of our salaries or the size of our automobiles, rather than by the quality of our service and relationship to humanity.

Success comes from failure, not from memorizing the right answers.

Judge your success by what you had to give up in order to get it.

The very first essential for success is a perpetually constant and regular employment of violence.

He who would live must fight. He who doesn't wish to fight ... has not the right to exist.

I know of no single formula for success, but over the years I have observed that some attributes of leadership are universal, and are often about finding ways of encouraging people to combine their efforts, their talents, their insights, their enthusiasm and their inspiration, to work together.
