Never set limits, go after your dreams, don't be afraid to push the boundaries. And laugh a lot - it's good for you!

Don't let your dreams be dreams.

I never plan to run at a certain pace. All my career my motto has been 'no limits.' I don't try to run with a set time in mind, sticking to set splits, because what happens if you're ahead of your splits - are you going to slow down?

Believe in and follow your dreams.

Don't give up on your dreams, or your dreams will give up on you.

I think when you move past your fear and you go after your dreams wholeheartedly, you become free.
