She may have initially made her mark playing New Yorker Rachel Green on Friends, but that doesn't mean the Big Apple was the right place for Jennifer Aniston.

"We tried New York," the Wanderlust star, referring to herself and Justin Theroux, said Friday on Australian radio's The Kyle and Jackie O Show in Sydney, but "it felt like I was [living] in a fishbowl."

And while, "Justin still has an apartment there … It was a little rough with the paparazzi. It didn't feel like the New York I grew up in and knew," notes Aniston, 43, who now calls L.A. home.

As a result, Aniston's current happiness level is at "10-plus," she says, and her Zen approach to life is also a contributing factor.

"You have a more relaxed sense of the world and life," she explains, "and you realize there's nothing to be taken too seriously besides doing your work and being a really good person."
