Whatever you do, you need courage. Whatever course you decide upon, there is always someone to tell you that you are wrong. There are always difficulties arising that tempt you to believe your critics are right. To map out a course of action and follow it to an end requires some of the same courage that a soldier needs. Peace has its victories, but it takes brave men and women to win them.
Ralph Waldo EmersonYou must elect your work; you shall take what your brains can, and drop all the rest. Only so can that amount of vital force accumulate which can make the step from knowing to doing. No matter how much faculty of idle seeing a man has, the step from knowing to doing is rarely taken. It is a step out of a chalk circle of imbecility into fruitfulness.
Ralph Waldo Emerson
