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.

Get out there and do what you love!

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

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

Watching the world's best compete fires you up to achieve your own feats of greatness. When it comes to running, participation and spectating go hand in hand.

Don't be ashamed or embarrassed to dream big. You're living your life with hope, that's a powerful thing.

Never underestimate the power that one good workout can have on your mind. Keeping the dream alive is half the battle.
