Jim Carrey
When Carrey was 14 years old, his father lost his job, and his family hit rough times. They moved into a VW van on a relative’s lawn, and the young aspiring comedian—who was so dedicated to his craft that he mailed his resume to The Carroll Burnett Show just a few years earlier, at age 10—took an eight-hours-per-day factory job after school to help make ends meet.
