Fear is something that we have all experienced, and this feeling can range from mild apprehension to terror so deep that it paralyzes. Facing your fears can help you overcome them, especially if these are excessive or very severe. Even heroes feel fear, it is how you act in spite of this emotion that determines whether you are courageous or a coward.
A just fear of an imminent danger, though there be no blow given, is a lawful cause of war
Let the fear of danger be a spur to prevent it; he that fears not, gives advantage to the danger
Fear is sharp-sighted and can see things under ground and much more in the skies
No person who is enthusiastic about his work has anything to fear from life
