Calling up your friends

We recently spoke to a mentor who had started a successful service-based company. He had recently sold his business for over $300M. We asked him how he had gained his first customers. "Well," he said, "I started the business when I was 50 years old". We looked at each other then looked back at him as he continued, "I just called up all my friends".

The lesson here? What kind of relationships are you building for yourself for the company you will start in ten or even twenty years time?
