I recently saw one of Shah Rukh Khan’s interviews.

He was asked by Anupam Kher in his show, about the secret to his success. 

SRK replied: I work very hard.
Anupam Kher said: isn’t that what everyone does?

SRK’s response? “Everyone works hard to get that one chance in life. However, I work as hard as I can after getting that one chance. “

And no one, absolutely no one works as hard as him, on every opportunity he has gotten. This is what makes SRK, SRK! 

(Fun fact: SRK even remembers the conversations with journalists, even when they interview him years later. For late night interviews at his place Mannat, he asks every journalist leaving, about how they are going to travel back home. Wow. Just wow.)
