The actress sits down with her “We’re the Millers” costar, Jason Sudeikis, for the September issue of Glamour magazine.

The former Friends star opens up about her fiancé Justin Theroux and how she found happiness.

“Thirties. Thirties,” Jen said. “Go to therapy. Clean up all of the s–t. Clean up all of the toxins and the noise. Understand who you are. Educate yourself on the self.”

“You can undo a lot of things,” she continued. “If you’re not happy, you can become happy. Happiness is a choice. That’s the thing I really feel. Like with friends who refuse to get happy, who refuse to rise above the discomfort of where they’re at.”

“In the movie, your character is learning to access her parental instincts,” Sudeikis told Aniston about her role in the movie We’re the Millers. “I would argue women are better at that.”

“I think that’s just you! I know Justin, for instance, has extremely amazing paternal instincts,” she said of her fiancé Justin Theroux. “Because [growing up] he had to sort of become the parent. I think when you have to become the parent when you’re a younger person, you learn those instincts.”

“You actually deserve to have a family,” Aniston said. “And once you meet yourself, and truly love yourself, then you attract that. And look — I mean, the two of us have found these two, beautiful, loving, open people.”
