My dream was always to win in the Olympic Games, but I never set that next goal, and I have realised now I need to set another goal.

I'm trying to focus on the 100 and 200 breaststroke now. There's no point concentrating on the 50 when it's not in the Olympics. I'm not going to quit the 50 but it's not my priority any more. I'll do it but as part of my bid for gold at the other distances.

I cannot control what goes on in another lane and this is how I focus on the Games. There is no point in being nervous of other swimmers. It's just about focusing on yourself and what you need to do in order to perform at your best.

I woke up on the plane this morning and was turning on my phone and I had to put my pin number in. That's when I realized that since the age of 10 I've been using 2012 as my pin number. But now that I've won gold in the 2012 Olympics, I've achieved that goal and, for the first time in 14 years, I'll have to change my pin.

I've got an opportunity that not many people have - to be the leader of Team Sky as I enter the prime years of my career.

We say women have made great strides: in biology, in many areas of chemistry, in many places, women are now the majority of medical students. But when I began my career, that wasn't the case. There were very strong stereotypes in biology and medicine.

I'm fully aware of how lucky I am to do the work I do. I work really, really hard, and there are a lot of privileges and perks that come with the job.

Coming back to Delhi is always special. This is the place I'd started my journey from and became independent. Be it my career or my education, I learnt everything about life from this city, and it has made me who I am today.
