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.
You can't become a winner overnight, or even in a couple of years-it takes time... You will lose races and you will have to accept that, learn from it and believe that you'll win the next one, knowing that you'll probably lose that as well. All the time you have to keep believing that one day you will win.
If I start planning then that's dangerous because then I have a target that I'm blinkered towards and I won't listen to the warning signs quite so much. I'd rather be in shape and then look around and say there's a race next week and jump into that than have it planned.
You can wish as hard as you like but all that really matters is the shape you're in on the day of the race. I've always felt these really big races aren't necessarily won by whoever is the fastest. They're won by the athlete who is the smartest and in the best shape on the day.
Doing the long endurance stuff seems to have given me the strength to sustain the speed. I think my body is just a lot stronger (thanks to the marathon)... By increasing the long runs, I found that does not take anything away from the speed but increases the strength on the track.
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.
