Unless you're not pushing yourself, you're not living to the fullest. You can't be afraid to fail, but unless you fail, you haven't pushed hard enough."

Adventure books are my personal favorites. 'The Endurance,' a story about Ernest Shackleton's legendary Antarctica expedition, or 'Into Thin Air,' Jon Krakauer's personal account of the 1996 disaster on Mt Everest, are two notables.

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.

There is magic in misery. Just ask any runner.

A Marathon is not about running, it is about salvation. We spend so much of our lives doubting ourselves, thinking we're not good enough, not strong enough, not made of the right stuff. The Marathon is an opportunity for redemption. "Opportunity," because the outcome is uncertain. "Opportunity," because it is up to you, and only you, to make it happen; only you can turn your farfetched dream into a reality.

Don't run with your legs, run with your heart.

Regardless of how distant your dreams may seem, every second counts.
