If someone has an idea that no one buys into, then that is the way it is. That is what a democracy, or partnership, is all about. I have seen too many start-up companies battle with internal problems because difference and diversity could not be exploited to everyone's benefit. And you don't want that. That is no way to solve things.
Balance is the key.
This exercise also provides a good lesson in perspective. If someone in your organisation thinks that the worst thing in the company is his or her parking space, for example, then I would say such a person lacks perspective. I have seen this in many companies. I have heard people talk about good and bad things in terms of this kind of internal perspective. If the fact that your parking bay is the furthest from the elevator continues to drive you mad, I would say your life lacks real challenges.
