"Apart from sports, enduring strength means that the business man shall stand, without a breakdown, business cares and worries, that he shall be capable, when necessary, of working morning, afternoon and night with unflagging energy, holding tightly in his grasp the reins of business, retaining all the while  a clear mind and untiring energy, both of body and brain.

The man who can miss a night's rest or miss a meal or two without showing any ill effect or without losing any physical power, is better entitled to be considered a strong man than the man who is only apparently strong, being possessed of momentary strength, which is, after all, a muscle test pure and simple."

"Greatness is not a function of circumstance.  Greatness, it turns out, is largely a matter of conscious choice and discipline."
