I apologise to people when I need to.
I have achieved a lot and I'm grateful for that - I'm just a bit greedy because I want to add the Olympics. It's once every four years - everyone wants it and very few people get it.
It's important that athletes can compete on a level playing field. And youngsters coming into the sport can know that if they are working hard and training hard, they'll see a true reflection of where they stand and what they can achieve worldwide and not be swayed by people who are cheating.
Plenty of people who are 38 have run really well in the marathon.
An Olympic medal won't define my whole life, although it might look like it to onlookers. When I look back, I should have been able to get an Olympic medal.
I am not going to let Athens affect the rest of my life.
A half marathon is a good way to have a bit of fun and race against those girls and learn a bit more about them.The world half marathon is a world championship at the end of the day and it's important. I've win it twice and it's a quality event.
I am not driven by any bitterness by what happened in Athens. I learnt a lot of lessons from it and probably came through it a stronger person in the end. There have been a lot of near misses, and that's taught me to keep persevering and that there is a chance it can come right.
Every time I go out and race it's a goal to go out and run faster than I've done before.
I cry all the time.
There's always going to be somebody who takes a dislike to you and you can't waste time worrying about it.
To represent your country at a home Olympics is something special and I'm over the moon to be selected for Team GB. I was pleased to get the qualifying time in Berlin earlier this year and my sole focus is getting in the right shape for London.
I have always loved running on the roads, ever since I used to take part in relays for my club when I was 12 and 13. I felt really at home on the surface.
In my Olympic history I don't think I have achieved my potential as an athlete. That's what I want when I look back at my career. I want to be able to say I gave it my best shot.
Actually I don't choose to expose myself in public. I choose to compete; the other side just comes with the package.
