Tell me a story, but not about you. Tell me a story that could be about you, but is about me and everyone else. Sing me one song about love for every five songs about something else. Make me laugh, then make me think, then make me go "yes!" Communicate with me and the rest of the audience. Don't think you're doing something wonderful and deep and precious, it's just a song!
But if you get it right, I'll never forget it...or you.
