He may be a superstar for his fans and critics alike but as per actor Shah Rukh Khan, there are moments in his life when he feels like a "loser", something that only pushes him to work harder. "I feel like a loser over everything. I was with Aamir Khan the other day. And he asked me 'Why are you like this, Shah? Why do you think this way?' I got to know after talking that he was also thinking the same way. He wasn't asking me out of surprise, he wanted to know the answers for himself," Shah Rukh said on Friday at the trailer launch of his upcoming film Zero.

The 53-year-old superstar believes it is "always important to have lack of over confidence". "Over confidence is worse than feeling like a loser. I feel I work harder when I think I am not good enough. I always feel I'm not good enough. I sometimes joke that I don't know how to dance, I've five expressions but I genuinely believe them, that I'm not good at everything, so I've to work harder," he said.
