The 2012 London Olympic Games fostered a generation of hope. I witnessed women participating for the very first time, representing every nation.

There are many women who came before me who didn't really have the same opportunities that I have had. That's why I always wanted to be a great ambassador - not only today's generation - but for the women who really didn't have a voice, but who paved the way for me.

I'm a realist and I always have been.

The London games mark the 24th anniversary of my winning two golds and setting the world record in the heptathlon. Someone is going to want it; records are made to be broken - it's only a matter of time. I hope mine will outlive me.

Getting started as a volunteer anywhere can be a challenge to a lot of people. The biggest hurdle is that people think they have to give all of their spare time. But if you only have a half hour, you can still make a difference. Assisting with small tasks is invaluable.

I'm not shy. I'm modest, but I'm very outgoing.

I'm always challenged by someone.
