Billy Ray Cyrus Wants Miley Cyrus to "Be Happy" Billy Ray Cyrus has only one goal in mind for his daughter Miley: be happy. "We've always had a slogan in our family: 'If you ain't happy, it ain't working,'" he shares in a new interview. He goes on to say, "You need to love what you're doing. . . . As long as she's happy and loving making music – and I know she loves acting – that's all that matters."
