stuff syndrome

I was recently previewing a nooma dvd online and came across this concept. that we live in a world that is setup to make you want what you dont have. And so we get focused so much on those things that other people have, that we lose sight of what we've got. I made me think a little bit and wont share all of that here for length, but this short snipit came to mind and was worth sharing.

It is very likely that wanting the things I don't have has led me to have all the things I dont want

That is, I look around and I do see all this stuff that I dont need or even want and it should make we wonder - why do I have it in the first place? I must have wanted at some point, right? Was it something I needed at the time, or was it simply something I didn't have?
