Peanut butter sandwiches

At a meeting recently, a business speaker told this story...

A workman sat down for lunch with his workmates and open his lunch box. "Peanut butter sandwiches again" he announced.

"Why don't you tell your wife you want something different" offered a workmate.

"I make them myself" said the workman.

This story made the room laugh, until the speaker suggested that we are often like the workman who want to change but never make the effort of changing.
