A relentless worker that he is, Shah Rukh Khan often goes the extra mile to achieve success as he fears losing the top position.
The 47-year-old superstar, whose last release 'Chennai Express' is one of the highest grossers at the box-office till date, said he is constantly working hard to sustain his place in the industry.
"I am scared of losing. I am scared of coming second. I am scared of not making it big. So, I have such a fear of failure that I work harder when even I don't need to. I work longer when I don't have to."
"I never rest on my laurels because I feel that this will be taken away one day. I have this fear that if I don't work hard enough I will lose what I have attained and not be able to continue to do so. I don't have blood pressure neither I am a heart victim but I need to just work hard," he said on the sidelines of 40th National Management Convention by All India Management Association (AIMA).
A star in the industry for two decades, Shah Rukh said that his journey has not been a cakewalk and he did face his share of failures.
But now basking in the success of 'Chennai Express', the actor said he has made many foes in the industry after doing the Rohit Shetty film.
"Failures also gets you to find who your real friends are. The true strength of your relationship gets tested in the phase of strong adversity. I lost lots of friends post 'RA.One', apart from losing a lot of audience too. And after 'Chennai Express', I haven't made any new friends but I have a whole new set of enemies now," he added.
Shah Rukh Khan sported grey streaks at the event which he said is a part of his look for his upcoming Farah Khan directed film "Happy New Year".
Having given many hit films including 'Darr', 'Baazigar',
'Dilwale Dulhaniya Le jayenge', 'Kuch Kuch Hota Hai' and 'Chak
De' among others, Shah Rukh Khan he said that he still feels like a newcomer on the sets.
"When I look at a project, I feel I don't know anything and I begin the film as a newcomer. I take it as my last project and give all my efforts to make it big so that I don't repent later," he said.
