You think your way is best, and you feel like someone is getting in your way if they're disagreeing with you. You have to compromise, and sometimes you don't want to compromise. I think it's much, much, much easier now because we have evolved as human beings and as artists. When you're in your 20s it's like, "No, these are my feelings and they are sacred and no-one must disagree with them," but having children, being married, having some wisdom and experience that comes with time allows you to collaborate, I think, in a way that you couldn't before.
