A true story comes from an incident which occurred during a business training seminar.To illustrate motivation,the trainer asked one of the business executives in the audience to come forward.
The trainer said,"I want you to imagine that I have placed a wooden beam across the floor here and I would like for you to walk from one end of the beam to the other end.Would you do that for $20?"
The man said that he would.
Then leader continued,"Now,I want you to imagine that I take that same beam and raise it up to the top of a forty-story building and run it across the street to another tall building.Would you still walk across the beam for $20?"
This time the man answered that he would not.
"How about for a $100?"
"No!" the man emphasized.
The trainer forged ahead."You have a child,right?"
"Yes."
"This time,what if I were to hold your child over the edge of the building and tell you that if you do not walk across the beam I will drop your child.Would you walk across?"
Surprisingly,the father hesitated for a beat,then smiled and asked,"Which child do you have?"
The trainer,of course,was right in assuming that a parent's devotion to a child is usually greater than almost any amount of fear associated with saving that child.Most parents love their children fiercely and would do anything possible to help them.
