Ever since I was a kid, whatever situation I was presented with, I always made the most of it.

I am an education ambassador, mainly working with schools.

When you're walking into the stadium, you just say to yourself, 'the 100m is the same anywhere, the shot put is the same weight anywhere.'

In my heart of hearts my motivation would always have been to be the best, and I think that athletics is probably what I was built for.

Retiring was hard. I'd spent 15 years doing something I loved, but when you get older everything seems to go. When I started spending too long with the physio and the doctor, I knew it was time to call it a day. But I had no preparation for being retired and I didn't know what to do.

There's no day when I don't think it would be great to be 25 years old and have the Olympics coming in less than 300 days - and be the best in the world. I can't think of anything so motivating.

What used to drive me was the fact that I wanted to be better than everybody at something. One of my best qualities is that I used whatever other people found to be an adverse thing to be a positive thing for myself.
