I guess I'm grateful that I cannot identify with that. My tastes are simple, I am easily amused, I like things without needing to have the best.
I am glad that there are people who are never satisfied; they are the ones who drive manufacturing and R&D to new heights, in areas like computers, audio gear, and photography; and I am one of the beneficiaries of that drive, albeit years down the road as the once cutting edge equipment becomes mundane and middle-of-the-road (and affordable).
But I'm just not in constant turmoil, searching for the next mountain to climb.
What I find somewhat interesting is that those who are in such a state seem to have no ability to recognize that others are not. They assume everyone is just like they are. Those of us who are, shall I say, more 'laid back' are well aware that there are those who must race ahead. You guys go on, we'll catch up later; or not.
