"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."
"We learn wisdom from failure much more than from success. We often discover what will do, by finding out what will not do; and probably he who never made a mistake never made a discovery."
"It is a mistake to suppose that men succeed through success; they much oftener succeed through failures. Precept, study, advice, and example could never have taught them so well as failure has done."
"Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to take rank with those poor spirits who neither enjoy much nor suffer much, because they live in the gray twilight that knows not victory nor defeat."
