Raymond B. Fosdick

The only life worth living is the adventurous life. Of such a life the dominant characteristic is that it is unafraid. It is unafraid of what other people think...It does not adapt either its pace or its objectives to the pace and objectives of its neighbors. It thinks its own thoughts, it reads its own books. It develops its own hobbies, and it is governed by its own conscience. The herd may graze where it pleases or stampede where it pleases, but he who lives the adventurous life will remain unafraid when he finds himself alone.

It is always the minorities that hold the key of progess it is always through those who are unafraid to be different that advance comes to human society.
