Emerson
Whatever you do, you need courage. Whatever course you decide upon, there is always someone to tell you you are wrong. There are always difficulties arising which tempt you to believe that your critics are right. To map out a course of action and follow it to the end, requires some of the same courage which a soldier needs. Peace has its victories, but it takes brave men to win them.
Alfred North Whitehead
True courage is not the brutal force of vulgar heroes, but the firm resolve of virtue and reason.
