You need courage to be different in this world addicted to being ordinary. When you talk like everyone, when you dress like everyone, when you do that is accepted by everyone, when you behave and take decisions based on others expectations, when you are slave to the external factors of the world that you are living in, then you are mellowed down anyway. You have submitted to the life you are given and do not need any courage to live your life. You are in auto-pilot and life will take you as per its will.
