The 27-year-old Oscar-winning actress said her mother had reservations about her chosen career path and she still gets worried, reported Femalefirst.
"When I was starting out, my mother would constantly ask me if I was sure about my career choice. Every time she did that, I would get annoyed but as I gain more experience, the more I understand why she kept asking me," Vikander said.
The actress feels one needs to love acting to survive in the profession.
"Even now I'm still constantly questioning the work I'm doing and going through moments where I feel insecure or uncomfortable. And I'm still very nervous every time I take on a new role," she said.
The "Jason Bourne" actress thinks she has been much more successful than she ever expected.
"I thought that if I worked hard on my English that I would be able to find work in American movies and moving to London was an important step so that I could become comfortable working in another language. But I still have the feeling that I need to work very hard," she said.
