A mid-sized company was having a terrible time with its internal mail system. People were constantly complaining that they weren't getting their mail. After about a month of this, the president of the company decided to look into the matter himself.
He went down to the mailroom, expecting to see a bunch of workers goofing off. That wasn't the case, though. There was only one worker in the mailroom, a young man who obviously enjoyed his work.
Envelopes were flying out of his hand into mail slots, and the entire time he worked, he sang and laughed and whistled.
"Young man," said the boss, "I want to commend you on the way you work."
"Oh," replied the young man, a big smile on his face. "To me, this isn't work .Its fun."
"What I wouldn't give to have 50 more people with your attitude," replied the boss. "And, like I always say, it's obvious that when someone enjoys his job, he is much better at it. I've never seen anyone sort mail as fast as you."
"Well, this is nothing," replied the young man. "Wait until you see how fast I get after I learn to read."
Point: "Quality depends on attention to detail" is the point of this story.
