Los Angeles: Actress Drew Barrymore believes in working hard to achieve something in life.
While covering More magazine, Barrymore opens up about women trying to accomplish it all, reports eonline.com.
"I'll get in trouble for it, but I'll say it anyway: Women can't do it all. Quantum physics actually says you can't do it all," said Barrymore.
"Like, you can't do everything at every minute of every day; it's actually not mathematically, molecularly plausible.
"(However), I do think that women can do everything they want to do, especially if they work hard enough at it. I don't believe anything comes easy. You have to earn everything in life," she added.
