Ashley Greene snubbed the Hollywood social scene when she first arrived in Los Angeles as she feared it would derail her chances of starring on the big screen.
The Twilight star dreamed of being an actress when she was growing up in Jacksonville, Florida and she moved to L.A. as a teenager to pursue her goal.
Greene admits the "glitz and glamour" of Hollywood almost pulled her into a life of partying - but she resisted temptation to focus on her auditions.
She tells Lucky magazine, "I was like 'Oh, I can go out and do this and do that,' and it took me about five seconds to realise 'If you do that, you're not going to book jobs, and there are 10,000 girls who want your job'.
"It's all glitz and glamour in Hollywood, and you want to be part of it. And the deadly thing is that you meet people who do have the money and do have fame and are in a position to not spend every waking moment working toward getting a job, and it's easy to feel like you can do it too, when really you haven't earned it.
"You can either socialise or you can study your script, and luckily I learned that pretty quick!"
