Many years ago a friend of mine had a ring I really liked. Too expensive for me back then. Over the years I sometimes searched for it on ebay and so... but hadn't enough money for spending it for such a needless thing.
Several years later I had the money and I bought it. I was happy for about 4 minutes, maybe less. I think I never really was happy about the ring itself, just about owning it finally. It had lost it's worth to me, when it became an object in my hands instead of a dream.
Since then, I like the feeling, NOT buying something, I really wanna have, much more. Also saves a lot of money. ;)
