Courage is the quality that we describe by it an army leader who confronted a huge army with only few soldiers to defend something dear to them, a person who risked his life to save a child from drowning, a fireman that rushes into the burning house to save its inhabitants from being burned alive, .....And many other situations that we find ourselves saying "Oh how courageous" and for a split of a second we wish that we were in those people places but the biggest question is "will we react as they did in that situation?" I think that by this question we can really define courage.
Some may say that a man with no fear is a courageous man and only when a person fears nothing then we can say that he's got courage, well as charming it may seems it is absolutely WRONG, you may ask why? If you fear nothing then u may do whatever you want, you can lead an army of ten people against a thousand, you can jump into a lava river to save someone,...Etc.
and if those are not courageous then who in the world is? Well the point is you can never have no fear at all and if you do then you are as they say "a man with no fear is a man with no brain"and I don't mean that you should fear for yourself cause fearing death has never prolonged someone's life not even a day long, as they say "cherish your life but don't fear death" so now one may ask "then what is the world should I fear for then if I'm dead then everything ends there is no me anymore " before saying that you should ask yourself one thing have you ever loved and cherished something more than you life if you haven't then believe me you haven't lived not even a single day and that what you should fear for (your loved ones) and here u can define a new perspective for courage from a person saving a live of a dear one to a fireman risking his life for people whom he doesn't know.
So after all that I think it is safe to say that courage is not having no fear at all but rather confronting these fears in order to do what is right and what you believe in so it is to rush into the jaws of death for what you believe in and you should fear no death if for the right cause.
