Actress Kiara Advani, who drew unprecedented attention with her performance in "Lust Stories", says she is now more responsible with her film choices and also more driven than ever.She made her acting debut with "Fugly" in 2014 and was later seen in films like "M.S. Dhoni: The Untold Story" and "Machine", but it was her part in filmmaker Karan Johar39s story in the "Lust Stories" anthology, which brought her wider visibility.Asked if she feels content with all the attention that she has got after "Lust Stories", Kiara told IANS here: "I feel more responsible with my choices now. I am more driven than ever and determined to work harder and to deliver. I want to make all those people proud who have put in so much faith in me.""Lust Stories" comprised four short film segments directed by four different directors: Anurag Kashyap, Zoya Akhtar, Dibakar Banerjee and Karan.Kiara portrayed a sexually dissatisfied wife who gets caught during self gratification by her family.The 26-year-old actress feels topics like self gratification, women39s desire and sex should now be spoken about openly and not behind closed doors."I think cinema is a reflection of the society and whatever is being shown is because of the climate we39re living in. It is relevant, topical and surely somewhere it39s impacting people who can relate to these circumstances," she added.With her acting debut in 2014, Kiara has only featured in five films. She said it was a conscious decision to take it slow."But that39s also because I wasn39t being offered every exciting film at that time. Today things are different and so I will work harder to keep that up now," she said.Kiara has now bagged two films -- Akshay Kumar-starrer "Good News" and Karan Johar39s "Kalank", featuring Sanjay Dutt.Happy with the developments in her career, she said: "I think the most important thing in life is to be happy. If you39re happy, it will show in everything that you do. What I39ve realised is that I39m happiest when I39m at work as I am always preparing myself for when the opportunity arises."I don39t stress about the outcome because I know the only thing I have control over is my own hard work. So long as I39m being honest about that and striving to be the best version of myself, I39m happy."Kiara spoke to IANS on the sidelines of the Lakme Fashion Week Winter/Festive 2018, where she walked the ramp for label Agami by Neha Agarwal."Neha is a fine talent and has a great aesthetic sense. She pays attention to details and her garments have a universal appeal," she said.On her fashion quotient, Kiara said: "For me, it39s more about how I feel and what makes me happy. I believe if you are happy in what you wear, you39ll radiate, and then that becomes a statement."
