Run when you can, walk if you have to, crawl if you must; just never give up.

When I ran across America, for 75 days I ate 10,000 calories a day. I still lost about five pounds.

I have my whole office set-up at waist level; I don't sit at all during the day. Sitting, to me, is the devil.

Sometimes you've got to go through hell to get to heaven.

As long as my heart's still in it, I'll keep going. If the passion's there, why stop?... There'll likely be a point of diminishing returns, a point where my strength will begin to wane. Until then, I'll just keep plodding onward, putting one foot in front of the other to the best of my ability. Smiling the entire time.

Some seek the comfort of their therapist's office, other head to the corner pub and dive into a pint, but I chose running as my therapy.

Struggling and suffering are the essence of a life worth living. If you're not pushing yourself beyond the comfort zone, if you're not demanding more from yourself - expanding and learning as you go - you're choosing a numb existence. You're denying yourself an extraordinary trip.
