Zac Efron Finds 'Structure' in Sobriety

"You get out of life what you put in," he said.

"What I found is structure," the “Neighbors 2: Sorority Rising” star said. "That led me to a balance of opposites: You get out of life what you put in."

Efron, 28, also reflected on the low times, when he was focused on things besides work and bettering himself.

Because he was so afraid and constantly in the public eye, he added, "A lot of my hobbies had gone out the window."

"I couldn't skateboard or surf for fear of being followed. Crossing the line of fear is what leads to greatness," he said.

The actor also tells the magazine that he'd be willing to bare all for the right role.

"Let's just say I'm not opposed to anything," he notes. "But if you're going to pull your d--- out, it'd better be for an Academy Award-winning movie."
