Mumbai, Nov 4 (IANS): An inspiration for many, Shah Rukh Khan says struggling actors should be concerned about their craft rather worrying about looks.

Asked whether he would like to give any tips to struggling actors, he said: "You have to work hard and focus on acting. Yes PR and portfolio are all important, but acting is more important. Focus on acting."

Now a superstar, Shah Rukh had entered the movies with "Deewana", in which he played a second fiddle, and worked his way up to be a superstar.

"Nobody becomes an actor by planning things. Don't focus on your clothes or make-up. Focus on your acting," he said on the sidelines of his birthday celebrations. SRK turned 49 Sunday.

The actor rose so high on the firmament that he was given the title of "Bollywood Badshah". The 49-year-old says he takes pride in being an outsider who made it big in filmdom.

Shah Rukh said: "I feel proud about the fact that I am an outsider. This industry has been harsh at times ... at times it loves you and at times it punishes you."

"There are a lot of people responsible for who I am today. I don't think I can ever play character Shah Rukh Khan in any film because I don't think my personal life is so important. I think I am too small a person and have a long way to go," added SRK.
