Hard work is the main thing-hard work and dedication. And I think a great part of it is goal setting. You set your goals to a point where they're attainable, but far enough away that you have to really go get them. And every year I push my goals a little bit farther away, and every year I work a little bit harder to get them. Every goal that I've set, I've been able to achieve. That's been very fulfilling.
