You gain strength, courage, and confidence by every experience in which you really stop to look fear in the face. You are able to say to yourself, 'I have lived through this horror. I can take the next thing that comes along.' The danger lies in refusing to face the fear, in not daring to come to grips with it. You must make yourself succeed every time. You must do the thing you think you cannot do.
