The 25-year-old actress said that she has experienced both high and lows since finding fame as Alice Cullen in the Twilight franchise.
She told People: "I don't [have regrets]. 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 shared that she focuses on her job and tries "to ignore a lot of things".
She starred in the new ABC pilot Americana, but the show was not picked up by the network.
