Willpower

Strength does not come from physical capacity. It comes from an indomitable will.

Mahatma Gandhi

Hidden strength

Beyond the very extreme of fatigue and distress, we may find amounts of ease and power we never dreamed ourselves to own; sources of strength never taxed at all because we never push through the obstruction.

Scott Jurek, adapted from William James

Getting things done!

I am a horse for a single harness, not cut out for tandem or teamwork … for well I know that in order to attain any definite goal, it is imperative that one person do the thinking and the commanding. 

ALBERT EINSTEIN
