Bravery is not something you;re born with, you get it as you gain life experiences. Bravery is what defines us. you can practice being brave by acting on what you brain pushes you to do and challenging yourself to deal in every situation. Even when you afraid, it is normal, just dont let the emotion takes control over yourself, we are emotion but what we want to do is to dicipline our emotion.
Bravery doesn't mean that you're never afraid. It means that you are afraid. But you move forward anyway, even in the scariest moments.
