Article on Trump's history as a 'manager'
Quote
In a book that O'Donnell wrote about his experience as a Trump casino executive, he painted a picture of a boss who was not interested in cultivating high rollers by socializing with them and unaware of the need for the repeat business of everyday gamblers from New York City and Philadelphia. What Trump was interested in was the way his executives looked and dressed. O'Donnell wrote of how Trump warned his top men about the dangers of losing their hair, and recalled that he once told all the managers at the casinos that they should wear suits because "there are no sport coats in the Trump Organization."

You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.
