Jennifer Aniston talks love, family and choosing happiness

Jennifer Aniston talks about finding love, choosing happiness and the advice she'd give her younger self in the September issue of Glamour.

The magazine interview was conducted by Jason Sudeikis, her co-star in the upcoming film "We're the Millers."

He asked Aniston, 44, to share what advice she'd give herself at various stages in her life. For her 30s, she replied, "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 added. "If you're not happy, you can become happy. Happiness is a choice. That's the thing I really feel."

At a point, she told Sudeikis, you realize "you actually deserve to have a family. 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." (Sudeikis is engaged to Olivia Wilde; Anistonto Justin Theroux.)

"We have a similar timeline," he told Aniston of their romantic lives. "We both went through the same thing. I mean, I would hear you talk about [guys you were dating], and I'd be like, 'Oh, f--k. I don't want to be like that to somebody else."

"Yeah. Yeah. And look how far we've come!" the former "Friends" star said. "High five!"

The September issue of Glamour hits newsstands Aug. 6. "We're the Millers" opens in theaters the next day.
