Feel the FEAR and do it anyway! Push through. We can run and always wonder what could have been. What happens if you get rejected for that job? You move on to another one -- possibly even a better one, even where you were meant to be! What happens if you reach out to that friend, even when you are scared to do so? You may save a life.
Acknowledge the fear, be grateful that it is there. Now push it aside and move forward. It is a choice.
