Barbra Streisand hated feeling rejected, and once told a casting director, "you'll be sorry." Sigmund Freud once told a childhood friend of his to save his letters. "You never know how important they will be," he said. Whether an actor, singer, psychologist or baseball player, there are some things ALL very successful people have in common: vision, resilience, ambition, and an unyielding belief in themselves. It's never easy getting from where you are to where you truly want to be, as you'll hear from multiple famous, successful people in this episode. The key to getting there? "Don't give up. Don't ever give up."
