Develop success from failures. Discouragement and failure are two of the surest stepping stones to success. The successful man will profit from his mistakes and try again in a different way. When you're afraid, keep your mind on what you have to do...if you have been thoroughly prepared, you will not be afraid. We all have possibilities we don't know about. We can do things we don't even dream we can do.
Dale CarnegieGood speakers usually find when they finish that there have been four versions of the speech: the one they delivered, the one they prepared, the one the newspapers say was delivered, and the one on the way home they wish they had delivered.
