Risk

"This nation was built by men who took risks - pioneers who were not afraid of the wilderness, business men who were not afraid of failure, scientists who were not afraid of the truth, thinkers who were not afraid of progress, dreamers who were not afraid of action."
~Brooks Atkinson

"It is not because things are difficult that we do not dare, it is because we do not dare that they are difficult."
~Seneca

"Do not be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better. What if they are a little course, and you may get your coat soiled or torn? What if you do fail, and get fairly rolled in the dirt once or twice. Up again, you shall never be so afraid of a tumble."
~Ralph Waldo Emerson

"Nothing will ever be attempted, if all possible objections must be first overcome."
~Samuel Johnson, Rasselas, 1759
