A novice asked the master: "I perceive that one computer company is much larger than all others. It towers above its competition like a giant among
dwarfs. Any one of its divisions could comprise an entire business. Why is this so?"

The master replied, "Why do you ask such foolish questions? That company is large because it is large. If it only made hardware, nobody would buy it. If it only made software, nobody would use it. If it only maintained systems, people would treat it like a servant. But because it combines all of these things, people think it one of the gods! By not seeking to strive, it conquers without effort."
