Natalie Dormer 'doesn't care' what people thinkLos Angeles, April 20 (AZINS) Actress Natalie Dormer says she is not worried about other people's opinions.

The "Game of Thrones" actress believes the key to survival in the showbiz industry is not to worry about other people's opinions, reports femalefirst.co.uk.

"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," Dormer told Stylist magazine.

The 33-year-old star admits her viewpoint has come along with age as she is much more "comfortable" with who she is now.

"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," she said.
