"At the age of 21, I was India's youngest film producer and that's a very major achievement for someone who is a main stream actor," the 42-year-old actor said.
"I was Alia's (her half-sister) age when I produced my first film and I don't think Alia would be able to produce a film today... She is a wonderful actor and a star but I am saying my aspirations were always slightly different," she said.
Pooja said even as an actor she avoided doing romantic films.
"I got lot to do at a pretty young age in terms of emotionally challenging films. I did not do any fluff... fluff is not me," the 'Dil Hai Ki Maanta Nahi' star said.
"I became a film maker because for me just being in front of the camera was not enough. I enjoyed making movies, creating new stars, enjoyed putting my films together and that's what gives me the satisfaction far more than just merely being a star," she said.
