From my years of charading as an athletic coach, I recollect the frequent banter among coaches when we would assess the propensity of an athlete to exhibit what is now often called grit.
Grit is a combination of character, determination, resilience, and refusal to give up.
The anecdote went something like this: If you fell over a cliff and your survival depended on one person at the top of the cliff holding onto your lifeline, would you want _____?_____ holding that rope?
Though we rarely get into literal cliffhanging jams in life, the figurative kind come along with a fair amount of frequency. Having someone at the top of the cliff who'll "hold the rope" is just as important in the figurative cliffhangers as in the literal.
Know the folks you want holding your rope?
