At the risk of pontificating, here are my 5 cents:
Today's Western society does not adequately support the development of things that are intrinsically fulfilling; solid relationships with friends and family, gentle reflection and self-discovery, giving to others, and growth. Many people therefore feel a low level chronic sense of anxiety or inadequacy. We often do not feel 'known' to ourselves or to others.
At the same time, consumerism gives the appearance that everyone else is perpetually happy. It promises us the means to achieve that same happiness by buying their products or services. Buying something these days rarely means enjoying your own experience. Instead it means being handled to have the experience a marketer intends everyone to have. Apple gloriously provides An Unpacking Experience. Movie theaters bombard you from entry to exit with The Next Packaged Experience (Movie X with Food Combo Y).
While contemplating said purpose, we have a temporary sense of control. That's why some people obsess for hours and pour over small details. When we purchase the desired object, we may feel a temporary sense of completeness or joy. Some people imagine that everyone is looking at them as they pull out the laptop for the first time. Some people admire the perfection of the objection as a narcissist would admire their own reflection. There is a cost, however. People can become upset when the desired object does not produce a permanent sense of completeness. Some people obsess about keeping their possessions perfect. They polish and protect. They fret over every little scratch. They protect their things as they would protect their own self-esteem. They fret when the next product cycle comes and they don't own the latest and greatest.
Owning something does not provide true happiness but our experiences reinforce over and over again that they MIGHT. Perhaps the next car. Perhaps the bigger house. If you're anything like me, looking back, believing that owning something would make me happy has only in the long term made me feel less adequate.
Take a deep breath. Go for a walk. Laugh. Turn off the TV. Breathe. Give something away. Really listen to a friend. Nurture the things that really make people happy and owning things won't mean so much.
Best of luck!
P.S. Does anyone know when the Mac Tablet is coming out?? Just kidding! Kind of.
