I think it's when I won the Youth Olympics I thought, 'I can really get gold in London.'

It's amazing to get one Olympic gold, but you have to be a legend to get two. And that's definitely my aim.

I now have Youth Olympic, Olympic and European Games titles, which is a dream. I didn't fight that well and just scraped through a lot of the fights, but winning is a relief, and it's more points towards the Rio Olympics, which takes a bit of pressure off me.

I used to be a person who just peaked for the big events, not doing too many competitions, but now you've got to go round chasing all the points because if you're not taking them, someone else is.

Whatever our bedtime was as kids, we could stay up an extra half hour if we were reading. My parents didn't care as long as I was under the spell of a Stephen King or a Douglas Adams. Now I read in bed. I read at work. I read standing in line. It's like, 'Hello, my name is Nathan and I am a reader.'

Coming back to Guess is so natural for me; they're my family. I always love being back, and to be able to come home and be in Malibu across the street from my high school shooting this campaign is absolutely amazing and just feels like the right thing.

The ultimate goal of any athlete in any sport is to become a true world champion.

I didn't do anything special after the French Open, after winning the tournament. I just had a nice dinner with my team and family, but I was so exhausted that I went to sleep early and couldn't stay up.
