Efron was flown to Brisbane, Australia from Papua New Guinea on a 'life-or-death flight' with the assistance of medical professionals.
Actor Zac Efron says he doesn’t have any regrets about his mistakes.
Efron has confessed to making numerous errors earlier in his career, but he thinks his mistakes have all been part of a maturation process, reports dailymail.co.uk.
“I’ve done a lot of things that I look back on and go ‘sheesh, are you kidding, what were you thinking?’ It is weird to say because I am also happy that I did all of those things because I am here before you today able to proclaim that this is me and I am very proud of who I am,” Efron said.
“We want to achieve that ability to say this is me and feel that. But it is a fleeting moment. It is one that I know I am going to have to face tomorrow. Every day I wake up and I have to start with again the man in the mirror and it is like starting from square one all over again.
“You are never perfect, you wake up every day and there’s a new set of challenges,” he added.
