Schwarzenegger has had a highly successful business career. Following his move to the United States, Schwarzenegger became a "prolific goal setter" and would write his objectives at the start of the year on index cards, like starting a mail order business or buying a new car – and succeed in doing so. By the age of 30, Schwarzenegger was a millionaire, well before his career in Hollywood. His financial independence came from his success as a budding entrepreneur with a series of successful business ventures and investments.
