I train for around 3-4 hours everyday. It can go up to 6-7 hours when a competition is approaching.

I always try to see the good in everything, and that gives me strength. Even when I lost in the London Olympics quarterfinals, I said to myself, 'Don't lose heart, God has his own plans.' Actually, life just goes on; you have to accept whatever challenge you face and become stronger.

I knew very little or nothing about the Olympics. Having qualified was itself a big achievement for me, and then being there was quite overwhelming. Although I lost in the opening round, but the fact that I fought well was enough for me to take away from Athens.

I would've loved to dress Diana Vreeland. I just loved her work as a creative woman and as a business woman - unpredictable, exciting, fun, and very, very clever.
