Bravery could also mean to stand up against yourself in situations where oneself finds that they are doing something that contradicts to what they truly believe in. You are your worst enemy and there will be times where people will try to influence you into doing things you really don't want to do, or make you change your personality in order to fit their "criteria." Yes, you certainly have to stand up against this certain individual(s) but in all honesty, I feel that fight needs to first be battled within you. You should want yourself to stop being controlled by others and be the person that you want to be. Life is too short to let other people dictate the way you live.
