Jennifer Lawrence is the highest paid actress for so many reasons, and one of those is her work ethic.

The 25-year-old actress, who topped the Forbes 2015 highest paid actress by banking $52 million, has maintained a busy schedule since The Hunger Games first premiered in 2012. Her initial turn as Katniss Everdeen made her a megastar, but it was her hard work that has kept her as the A-list actress in Hollywood.

However, Jennifer Lawrence concedes that the intense work schedule has its own set of pitfalls.

“I try to keep working so people can see other characters and other things I can do instead of taking vacation time, and now I’m aging like a president,” Lawrence said at a press conference for The Hunger Games: Mockingjay – Part 2 on Saturday. “I hate waking up without a goal or going to sleep without achieving nothing.”

Lawrence said her popularity has allowed her the privilege of being picky when it comes to roles and she made a plat to prioritized taking on diverse roles in the wake of The Hunger Games to broaden her appeal.

That decision led Jennifer to a slew of roles of late, including her upcoming role in Joy, her third collaboration with director David O. Russell in four years.

“I remember there have been a few times where I would have loved time off,” she said. “But I was very aware of how overwhelming these movies and this character was, and that was a big fear of mine signing on to these movies.”

In Joy, Lawrence plays a single mother and inventor in the film, and ages through 40 years old. “David gets visions,” she told the New York Times of the casting. “He’s in his own beautiful, amazing world. Those kinds of silly questions [about age] don’t really matter to him. It’s not like I was old enough for American Hustle. And I was way too young for Silver Linings Playbook. That’s why I almost didn’t get it.”
