Charlize Theron has admitted that she has no idea how long she will remain an actress. According to Los Angeles Confidential magazine, the 36-year-old actress also revealed that it is the uncertainty of her profession that makes it all the more interesting. “I don’t know if I feel I’m here to stay, but that’s a good thing. That keeps you on your toes,” Contact music quoted her as saying. “I think this is an industry where you can’t get too comfortable. It’s constantly churning with great talent, and you’ve got to raise the bar and try to push yourself. I don’t ever want to kind of feel, ‘Yeah, I’m here. I made it.’ I think that would probably be the time to retire,” she added.
