Who are we supposed to be? What a question!
Don't ask yourself what the world needs; ask yourself what makes you come alive. And then go and do that. Because what the world needs is people who have come alive.
We all struggle with purpose and direction in life - but maybe the question isn't what we are supposed to be doing, maybe the question is who are we supposed to be? So often we end up failing others because we are trying to fit into their desire, or thoughts for, what we should be. Instead we should just get comfortable with who we are and work from there. Courage is what it takes to stand up and speak; courage is also what it takes to sit down and listen.
We don't always need the courage to stand up for others and defend what we believe, sometimes the best thing in the moment is to pay attention. It can be the best example of your faith and an easy way to share your beliefs when you are the one doing the listening.
