This is what we call a specialness spiral. You take an ordinary item and forgo using it once. Because of that, you start to see it as a little more special. But because you see it as a little more special, at the next opportunity to use it, you say, “Well, maybe this is not a good enough opportunity,” so you pass up using it. It becomes a little more special. The next opportunity has to be even better, which means that it’s less likely to be used, so it becomes even more special. It’s this ratcheting upward of a specialness spiral where an item that started out very ordinary, through repeated lack of use eventually becomes quite special and seen more as a treasure.
