"There's a stage of the business life cycle I call the go-go phase, when a company really takes off. The founder starts believing that everything he touches will turn to gold. He diversifies from shoes into shopping centers and electronics. He's like a child who begins to walk and suddenly finds everything interesting. You have to follow him around saying, 'No! No! No! No! No!' "
