Natalie Dormer "doesn't care" what people think of her.
The 'Game of Thrones' actress believes the key to survival in the TV and movie industry is not to worry about other people's opinions.
She said: "I wouldn't be upset about what people think of me.
"That's rule number one of surviving in this industry; don't care what people think.
"Just be true to yourself and be as pleasant and professional as you can.
"If you start caring what people think, you're screwed."
The 33-year-old star admits her viewpoint has come along with age as she is much more "comfortable" with who she is now than when she was a teenager.
She said: "That's the difference between being a 33-year-old woman and in your teens.
"You know who you are; you've gone through a lot to feel comfortable with who you are.
"Then for a while you pretend you don't care, and you still do.
"I think your early 30s is a very empowering age for women, you get your priorities in the right order."
Natalie believes she is a good listener, but can also be "devastatingly" funny.
She told Stylist magazine: "I'm one of those people who doesn't say something for months and then will say something devastatingly funny out of the blue.
"I'm more the listener. I'm quite an easy-going, fun person."
