United States
Ken Jennings is the highest-earning American game-show contestant ever, having won money on five different game shows, including $4,522,700 on Jeopardy!, which he now co-hosts. He believes that learning is a lifelong process, and that there is always something new to learn: "The more you learn, the more you realize how much you don't know. Embrace that feeling and keep learning."
