Scott Disick: I'm No Longer 'Selfish, Self-Centered'

http://img2.timeinc.net/people/i/2010/news/100308/kourtney-kardashian-240.jpgScott Disick says giving up alcohol hasn't just made him sober – it's also made him nicer.

"You know, I just realized there's bigger things in the world than just being a selfish, self-centered, pr–k," Disick, 27, told PEOPLE recently at the Famous Stars and Strikes Event benefiting A Place Called Home at Pinz Bowling Alley in Studio City, Calif.

Disick has sought professional help for alcohol and other issues, and says maintaining his sobriety is a daily battle. "There's times that it's difficult but, you know, the good outweighs the bad," he says. "It's nice having a healthier lifestyle than I used to have."

Kourtney Kardashian's off-again-on-again boyfriend, who makes an appearance on Kourtney & Kim Take New York and has a 1-year-old son, Mason, with the reality starlet, says his relationship with his family and Kourtney's is improving – but that's just the tip of the iceberg.

"I mean, I get along better, I think in general, with everybody in the world," he says. "Not only my family, but just even the surrounding people."
