Happiness never lays its finger on its pulse.
You have to have your wits about you and think quickly on your feet.
Winning Commonwealth gold was just totally unbelievable.
Stepping up a gear during any race is not an easy thing to do.
So when you put the kick in and the other runners go past you, it's game over!
It probably won't sink in until I've retired from running but I'm a much better athlete than two years ago.
It is a natural gift I was born with but it's something I've had to nurture in training.
If you see swarms of guys coming around you, you have to try and avoid being stuck on the kerb.
If you go too soon, you can come unstuck with 50m left when the guys are going past you.
If it's a slow race you have to be on your guard. You have to be patient, but I prefer that.
I first discovered my turn of pace when I was playing football as a kid.
I could produce spurts of speed and after taking up athletics I found myself running quite quickly over 400m.
Deciding on when to kick is crucial and depends on how the race is unfolding.
