New Delhi, Sept 28 (ANI): Though Bollywood Badshah's latest release 'Chennai Express' have set the new benchmark as far as box-office is concerned, but looks like SRK is still very restless. King Khan is not taking it easy after the remarkable success of Chennai Express. At a recent event Shahrukh confessed he doesn't take his failures lightly or his success for granted. "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.
