New Delhi: Actor Arjun Kapoor says he wants to push and reinvent himself with each role because he finds challenging characters fascinating. The 29-year-old star, who has starred in ‘Ishaqzaade’,’2 States’ and ‘Finding Fanny’ in his three-year-old career, says any character which is not close to his real-self excites him. “Any character that’s not me appeals to me. It is boring to play yourself and it is not easy also beyond a point to be yourself in front of the camera,” Arjun said in an interview.
