“I don’t [have regrets],” the actress, 25, told PEOPLE on Thursday at the Bing-sponsored Young Hollywood Awards. “Things have happened that have been unfortunate at times, but I feel like it’s really how you take that experience and learn from it and grow from it. Everyone has ups and downs. I try not to regret.”
Greene, who hosted the show at the Hollywood Athletic Club, says, “Keep calm and carry on,” is her motto for surviving the roller coaster ride of her career environment.
“I feel like when I was first kind of thrown into this industry and this whole world, it was a little overwhelming, and everything seemed like the end of the world sometimes,” she said. “You’re focused on every little thing, good and bad.”
Of her lessons learned, Greene says simply, “You kind of just have to ignore a lot of things and focus on your job and what makes you happy.”
