Acknowledge all of your small victories. They will eventually add up to something great.

You can't do in a race what you haven't prepared for.

Set small goals along the way and don't be overwhelmed by the process.

Racing is the fun part; it's the reward of all the hard work.

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

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 try to rush progress. Remember -- a step forward, no matter how small, is a step in the right direction. Keep believing.
