“I understood what I'm here to do and knew where to channel all this energy that has been coming at me. I now feel this sense of peace. People say that I'm different since I did it." Last year a video of the actress launching the HeForShe campaign at the United Nations went viral thanks to her powerful and moving speech.

"I was in my hotel room, thinking, I can’t do this,” the actress said, thinking back to the night before she delivered her speech. "I was just terrified. And then I Skyped a friend who said, 'Go through it again and ask yourself, if you were hit by a bus tomorrow, would you be comfortable with every single line?’"

Looking back on her acting career which began when she landed the role of Hermione Granger in the Harry Potter film series, Watson admitted she sometimes wonders why it all began. "It's something I've really wrestled with. I've gone back and I've quizzed my parents,” she confessed.

"When I was younger, I just did it. I just acted. It was just there. So now when I receive recognition for my acting, I feel incredibly uncomfortable. I tend to turn in on myself. I feel like an imposter… It was just something I did.” The full interview with Emma Watson appears in the September issue of Vogue.
