Tom Cruise is best known for the numerous hit films that he has acted in and the controversies regarding his personal life and beliefs that he has been involved in. While he has worked with renowned directors and actors from the entertainment industry throughout his career, his blunt advocacy of the Church of Scientology and its social programs has often got in the way of his personal and professional relationships. Furthermore, his belief in the ideologies of the cult has also made him criticize psychiatry as pseudoscience. Thankfully, he often focuses on his acting career, rather than the controversies, in his interviews. His quotes reflect his yearning for good challenges and his pride in achieving 'impossible missions' towards success.
