What is the worth of something?
I was thinking that it is either how much someone is willing to pay, or is it how much someone is willing to sell it for? Or is it the point where those two meet?
What if it doesn't meet? Say I had an object and would give it up for \$100, but if no one wants to buy it for that much, only say \$90, then what is it worth? Because I won't be selling it and no one will be buying it.
