Angelina Jolie "questioned her worth as a person" as a young actress. The Oscar-winning star was troubled with her choice of profession in her early 20s because she felt she wasn't "contributing anything."
Angelina told Parade magazine: "To be sitting doing an interview, talking about a movie, my relationships, or whatever it may have been - you don't feel like you're contributing anything.
"I have nothing against film. I like film. But at the end of the day, you wonder about your worth as a person."
Angelina, 32, who has admitted to suffering from a self-harm problem as a teenager, also revealed she had not "found her way" when her career took off.
She said: "I think that when I was in my early 20s, I knew, innately, that I wasn't living an important life. I think that I hadn't so much lost my way, but I hadn't found my way. I wasn't giving very much. My life was not really benefiting anyone. That just doesn't feel good."
The "A Mighty Heart" star recently revealed she wants to be remembered for her humanitarian work and not as an actress, saying she was "very unhappy, unhealthy and empty" before she took up her role as a UN Goodwill Ambassador.
Angelina, who has three adopted children and a biological daughter with her partner Brad Pitt, was appointed as a foreign policy leader on the Council on Foreign Relations (CFR) last Thursday.
