Musician Bruce Springsteen was interviewed this past week by The Daily Show's Trevor Noah:
Trevor: When you create, do you still have doubts sometimes?
Springsteen: Any good artist wrestles with their insecurities. It’s your insecurities that move you forward. If you were simply completely comfortable with who you are and what you’re doing and what you’ve done, I don’t know if you would have the fire in you to move forward. It’s your doubts and your questions and your searching for new and different answers that move you forward in your work.
