"It (self-doubt) is part of your being. If you don't have self-doubt you can't move ahead in life. You need to have some degree of insecurity or self-doubt, and you just can't be like you are the king of the world and do whatever comes your way," Rani told IANS. Questioning yourself is important, stresses the actress. "You have to have a little sense of questioning to basically try and achieve and keep achieving your goal. That can only happen when you doubt yourself a bit and push yourself harder towards your goal," she said. Rani made her Bollywood debut with the 1996 social drama "Raja Ki Aayegi Baraat". She was later seen in films such as "Ghulam", "Kuch Kuch Hota Hai", "Saathiya", "Hum Tum", "Veer-Zaara", "Black", "Bunty Aur Babli", "Kabhi Alvida Naa Kehna", "No One Killed Jessica", "Mardaani" and "Hichki".
