His advice to immigrant entrepreneurs: Don't let others' negativity discourage you from achieving your goals.
"Aw-nold" wasn't always a famous face with a big bank account. He's originally from Thal, Austria, and immigrated to the United States in 1968 at age 21. His meal ticket back then was body-building. Schwarzenegger would eventually become a five-time Mr. Universe and seven-time Mr. Olympia champion, which helped open many doors for him -- especially in Hollywood. From 1969 to 1980, he was cast in a series of small roles in films such as "Hercules in New York" and "Stay Hungry." When he was cast as the title character in the 1982 film "Conan the Barbarian," Schwarzenegger's acting career took off. He became a U.S. citizen in 1983. One year later, he starred in "The Terminator" and has gone on to star in more than 20 films.
Schwarzenegger's entrepreneurial ventures include the Arnold Sports Festival, which he started in 1989 and is held annually in Columbus, Ohio. It hosts thousands of international health and fitness professionals and has expanded into a three-day expo. He was one of the founding celebrity shareholders in the Planet Hollywood restaurant chain that opened in 1991. Schwarzenegger also owns Oak Productions, Inc., a movie production company, and Fitness Publications, a publishing interest with Simon & Schuster.
In 2003, he ran for governor of California, and won, ultimately serving two terms. Today, Schwarzenegger is worth an estimated $300 million. His films have grossed $1.6 billion domestically. In October, he published his memoir "Total Recall: My Unbelievably True Life Story."
Earlier this year, he was profiled in ESPN's "30 for 30" short documentary-film series. During that interview, Schwarzenegger discussed how early in his career, he refused to let naysayers stop him from pursuing his dreams: "I didn't pay any attention to it. . . I did not listen to the 'no' . . . and it worked out. I used that attitude as a blueprint for the rest of my life."
