Mumbai, Sep 6 : Actress-singer Priyanka Chopra, who has given hits like "Fashion" and "Barfi!", and worked with international singers like Will. iam and Pitbull, says she competes only with herself. And she admits she is critical of herself.

Priyanka also said she is not bothered by what her contemporaries in showbiz do.

"I am very critical of myself. Everybody says this 'I compete with myself' and I really do. You can call it my selfishness, but I am not at all interested in others' lives. Whatever my contemporaries do or not do, that has not influenced my career," Priyanka said in Mumbai.

As of now, she is content with her career graph.

"I am happy that I've always got to do good work. I have got good films and that has nothing to do with what anybody else does or not... I try and push myself as much as I can. I think I am very difficult competition for me," said Priyanka.

After making an impressive debut with "The Hero: Love Story Of A Spy" in 2003, the former Miss World went on to do many commercially successful films. She displayed her acting skills by playing a troubled model in "Fashion", a feisty Marathi woman in "Kaminey", a killer in "7 Khoon Maaf" and an autistic girl in "Barfi!".

Her latest film "Zanjeer" released Friday. And now she is geared up to play a boxer in a biopic based on Olympic medallist Mary Kom.

"Now, I have done good work in 'Barfi!'. I am thinking how it will be in 'Mary Kom'. So I do compete with myself," she said.(IANS)
