She is among the biggest stars in Hollywood and Charlize Theron credits her success to being an immigrant in USA. The Oscar-winning actor says as a young girl in Hollywood, she was aware about the fact that missing out on even one opportunity could be harmful to her career. "My dream was to pay my bills and not have to get a second job. I loved having the opportunities I got in acting, and I worked hard knowing that those opportunities could be fleeting."
