I grew up in business. My father was a serial entrepreneur and his lifelong dream was to build a business and run his own show. He never achieved the really big, breakthrough success that I think he desired, but he did okay. He was also one of the kindest, gentlest men one could ever meet, and he was truly loved by those who knew him, but that's a story for another time.
He had a lot of ups and downs in his business career but the one thing he could always count on was customer loyalty the likes of which is rarely seen today. My dad died when he was 72 years old, and he was still running his business right up to that last day. He had customers that were still active who had been with him nonstop for 40 years. You don't get that kind of loyalty without some pretty incredible level of dedication to customer service.
