MILK BOTTLE STORY
When Charles Wilson was president of GE, he was asked by the president of a small mid-western company how his experience as president of a major company could apply to the president of a very small company.
Wilson answered by detailing a job he had when he was a kid. He worked for a dairy and his job was to fill the milk bottles.
The bottles were different sizes. Some were pint, half gallon and others were gallons. They all had different size necks.
On his way home from a ten hour work day, he asked himself what he was learning. The answer was that no matter what size the bottle, the cream always came to the top.
