The 22-year-old feels she could have easily gone off the rails if it was not for being so busy, reported Showbizspy.
"I have work to occupy me so anything wild I might do is not going to happen. But that's nothing to do with acting or this lifestyle. I think I would be the same whatever I was doing. I like to work but if I wasn't doing anything then there could be a problem there," she said.
Stewart was recently seen in the film "Snow White and the Hunstman" opposite Charlize Theron and Chris Hemsworth.
