A lot of it is luck. You find yourself in a job, and you love it, and you stick with it, and that's your calling. I don't think you stand on the top of a mountain and throw your hands up to God and say, "What is my calling?" I don't think it works! You stumble on your calling. Whatever it is, whether you're a ladies' salesman in the garment center or a pit boss in Vegas or a comic, you need to be able to say, "I'm very comfortable doing this."
