The story is told of a local fitness center that was offering $1000 to anyone who could show they were stronger than the owner of the gym. Here’s how it worked: The muscle-bound owner would squeeze a lemon into a glass until all the juice was gone. Then he would hand the lemon to the challenger. Anyone who could squeeze just one more drop of juice from the lemon would win the money.
Over time many people tried to best the owner - other weightlifters, construction workers, even professional wrestlers but nobody could.
Then one day, a small, skinny man in a suit came in. He had come for other business, but when he heard about the challenge, he said he wanted to give it a try. When the laughter finally died down, the owner grabbed a lemon and squeezed away. Then he handed the wrinkled remains to the little man.
