" Courage is a defining factor in the life of any artist. The courage to bare your innermost feelings, to reveal your true voice, or to stand in front of an audience and lay it out there for the world to see. The emotional vulnerability that is often necessary to summon a great song can also work against you when sharing your song for the world to hear. This is the paralyzing conflict of any sensitive artist. A feeling I’ve experienced with every lyric I’ve sung to someone other than myself. Will they like it? Am I good enough? It is the courage to be yourself that bridges those opposing emotions, and when it does, magic can happen. "

― Dave Grohl , The Storyteller: Tales of Life and Music
