If you were to describe what it means to be a man in one word, what would it be and why?

"A man has to maintain character under various circumstances(scrutiny).  This is called stoic.  This requires a person to be very comfortable with one self.  He must know his identity and not adapt to carious circumstances.  To navigate this world and ones identity is to be stoic."
