Barbra Streisand, 78 years old

Streisand has so many awards that Beyoncé looks like a rookie next to her. Regarded as one of the greatest female artists in the world, she still has stage fright even after six decades of worldwide success and admiration. One might expect that she knows what she is capable of. However, she dislikes the sound of her voice and is still plagued with self-doubt. At 77, with a fortune of $640 million, she often agrees with her rarely negative voices. We find your self-criticism, despite your success, refreshing!
