Though, the 35-year-old actor comes from a filmy background, Gyllenhaal admits she is still not used to the cutthroat nature of Hollywood and has moments of doubt about her career, reported Contactmusic.
"I think I'm a lot less tough than I kinda act like I am. I do find the business tough but exciting, and I do enjoy my job. It gets me down but it also really, really takes me up. I like the ride of going through a project, but all the stuff around it can sometimes be really exciting, and sometimes not," she said.
