The allusion is made by the perspective

The reason we do not appreciate our lives is perspective. From our view our live is average, boring, and unexcited. Overtime we lose interest in most things. As a child we would wait and wait and wait to get that brand new car for Christmas, by the end of the week, we had forgotten all about it. We will always envy what we do not have, everything everyone else has is automatically more exciting than something we own. In our eyes our individual lives are boring and average compared to the next. It is so because we are so used to living this way. What we must realize that the people we may envy probably have the same view as us with their lives being boring and ultimately average to them. We get Chinese symbols tattooed on our skin because of how exotic an unknown they are. I have seen first hand the opposite being true just recently. It is what really got me thinking about how we view different things. Also when dealing with self pity perspective could really help to, for lack of a better phrase, put things into perspective.
