Actor Nawazuddin Siddiqui, who is basking in the appreciation coming his way for his performance in Shah Rukh Khan starrer "Raees", believes his journey as an actor has just begun. He says he has a long way to go. "Even though I have been in the industry since 2000, my acting career kind of took off in 2012 and it has been a very satisfying journey so far. But it has just begun and I have a long way to go," Nawazuddin, who doesn't like to dwell on success for too long, told media. With Rahul Dholakia-directed "Raees", he has worked with all the three Khans. He starred with Aamir Khan in "Sarfarosh" and "Talaash", and with Salman Khan in "Kick". Looking back at the experience of working with the three superstars, he said: "It's from them I learnt how to sustain one's position for long, with a variety of roles. The learning has been immense because of their vast experience. They are all great entertainers and that's proof to their popularity." Nawazuddin's performance was much talked about in "Raees", with most critics highlighting that he overshadowed King Khan.
