A speaker started off his speech 

by holding a $20 bill.

He asked: " Who wants this $20?"

Hands started going up.

He crumpled the bill, dropped it to the floor and ground it with his shoe.

He picked it up, crumpled and dirty.

Then he asked, "Now, who still wants this?"

Everybody's hand still raised.

"My friends, Let this be a lesson.

Others may trample upon you,

But they can never diminish 

your true value."
