Not everyone can be rich,' Peter went on. 'Not everyone can be strong or clever. Not everyone can be beautiful. But we can ALL be brave! If we tell ourselves we can do it; if we say to our hearts, 'don't jump about'; if we carry ourselves like heroes... we can all be brave! We can all look Danger in the face and be glad to meet it, and draw our swords and say, 'Have at you, Danger! You don't scare me!' Courage is just there for the taking; you don't need money to buy it. You don't need to go to school to learn it! Courage is the thing, isn't it? Don't you think so, people? Aren't I right? Courage is the thing! All goes if courage goes!
