I think it's sensible to plan for the future now I'm a father and a husband.
I like to think I have a good few years left of my career yet, as long as I stay fit and healthy. However, it's always good to have a backup plan, which is why I have been working hard to build my business portfolio outside tennis.
Against Steve Johnson at the Olympics I was down a couple of times.
I believe you should give 100% on the court, so I chase every ball.
I am still been pumped to train and get myself ready for the biggest events.
I've always been a good returner since my junior days - I don't know why that was.
