If you ever hope to succeed and grow, you must have a personal investment in experiencing that success and growth. In order to make the money you need in a sustainable way, you have to be happy about the way you're doing it. Companies are just groups of people. Unfortunately, this may not be as true for the emerging typical model for the multi-national corporate megaliths that lead our economy today. Behind every turning point in every process, no matter how big or small, there is a human mind, a human heart, and a human soul weighing or ignoring the ramifications of their actions.
Companies are subject to the same social laws as other groups of people.
If you can't get along with a certain kind of person in your personal life, you will not be able to get along with them in your business. If there's something about your potential business partner that annoys you when you have dinner together, it will drive you completely nuts when you're working together. If you don't treat your customers the way you treat people you care about, you will lose lots of customers. If someone can do something better, faster, cheaper than you, they will be more likely to succeed. If you are not being challenged and being creative, you will never really be happy.
