He has given back to back hits like "Taare Zameen Par", "Ghajini" and "3 Idiots" in the last three years but Bollywood actor Aamir Khan claims he has "no recipe" to make a successful film and he doesn't know what audiences want.

"I don't have any recipe (for success). Lot of us often forget that the business we are in by definition is basically selling stories... We have to be different each time. I have to reinvent myself, I have to be different - that's the demand of my job. It's not something that I am thinking and doing, " Aamir said.

"I am attracted to scripts that move me emotionally and when you have such stories to tell, it doesn't matter how unusual it is, people connect to it, " he added.

The 44-year-old who was here at the Economic Times Awards also stressed that he is oblivious to the audience demand in terms of content.

"I've no idea what audiences want. I only have an idea about what I want... When I read a script, I go with my gut and then it just happens, " he said.

Aamir's latest outing "3 Idiots" has smashed all records and become Hindi cinema's highest grosser till date with collections crossing Rs. 240 crore worldwide.
