Jennifer Aniston is proof that a successful career doesn't come without a few bad decisions.

In a new interview with American Harper's Bazaar, the actress talks about her lucrative career - according to Forbes she was the fifth highest paid actress in 2015 - shedding light on some of her regrets at work.

"There was a time when I worked and worked and worked. I loved it," she says, but she's now learning the art of saying no. "I'm trying to be better at that. I'm a bit of a people pleaser. I've got to stop. Some of the movies I've made, I bow my head in slight shame over."

At 47 years old, she says she "really [has] to love something to be leaving my home, my dogs, my husband. The older you get, the more you realise that."

With a CV seeped in hit comedies such as Friends, We're The Millers and Horrible Bosses, Aniston is ready for darker and edgier roles such as her lead part as a chronic-pain sufferer in 2014's Cake.

"People forget who actors are. They say, 'You're too known to play that part. You can't disappear.' And we're like, 'Give us a chance. We'll disappear.'"

"There's a steadiness, for sure, but also this desire to peel away more. You know, like 'F**k it.' "

"You have to start taking chances in an industry that's very insecure about taking chances on people," she adds.
