"I am working on a subject right now and all I can say is it's in the pipeline. I have to work a lot on the subject and yes there is a subject definitely that I am working on. I am somebody who never wastes time. I always want to learn something," Salma said in an interview.
"Whatever you learn, it will come with you and there is no age for education. I can't say whether it's related to my life but it's a women oriented subject. It's a little far yet," she added.
Salma debuted in Bollywood in 1982 with box office hit social drama "Nikaah" and she sang all her songs in the film, including the hit number "Dil ke armaan aansuon mein beh gaye".
She is also happy with her daughter Sasha Agha who is debuting with Arjun Kapoor-starrer "Aurangazeb".
"It's a very strange experience every time she comes on screen I get so excited I feel it's me. It's a totally confused state of mind. It's a reflection that I see," said the 46-year-old.
Salma also feels that the process of filmmaking has changed over the years and for the better.
"In today's days, the subjects that are being explored would not have worked 10 years back. Thanks to the filmmakers who have educated the public who are now accepting different cinema. There are some realistic films which are doing really well. Improvement is for the best," she said.
