"Every company goes through distinct phases as it grows. The smallest companies are customer-focused. Mid-sized companies are often employee-focused, as they build their internal systems to handle more business. The largest companies are always financially-focused, caring nothing about people and everything about numbers. A simple exercise shows why this is necessary. Look down your street, then look at your city from its tallest building, and finally look out the window of an airplane. Describing and serving the world from 30,000 feet demands mathematics, while working with the people on your street demands a personal touch."
