"Fear is like fire: If controlled it will help you; if uncontrolled, it will rise up and destroy you. Men's actions depend a great deal upon fear. We do things either because we enjoy doing them or because we are afraid not to do them. This sort of fear has not relation to physical or moral courage. It is inspired by the knowledge that we are not adequately prepared to face the future and the events it may bring - poverty perhaps, or injury, or death."
