There are a million reasons why you can't. Focus on the few reasons why you can.

Once you make the decision that you will not fail, the heart and the body will follow.

That's the thing about running: your greatest runs are rarely measured by racing success. They are moments in time when running allows you to see how wonderful your life it.

I try to think about positive things - how great my form is, how my arms are swinging, my breathing, how loud people are cheering. My sports psychologist taught me there are a million things telling you you can't keep going, but if you find the things that say you can, you're golden.

Progress is rarely a straight line. There are always bumps in the road, but you can make the choice to keep looking ahead.

As badly as I want a medal, I know there is a lot of luck involved in that. I want to put myself in position to be in the top three, give it my all and hope luck comes my way.

The journey isn't always perfect, but always worth taking.
