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

The only one who can tell you "You can't" is you. And you don't have to listen.-Nike

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.

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.

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

Any goal worth achieving involves an element of risk.
