"A thing is worth what it can do for you, not what you choose to pay for it"

This quote by John Ruskin is a tip that the value of something should not be figured out by the amount of money you are willing to spend for it. Rather, the worth of something need to be figured out by what it can do for you. This indicates that the effectiveness of something must be the main factor in determining its worth. For example, a cars and truck might be expensive, but if it can get you from point A to point B, then it is worth the expense. On the other hand, a piece of precious jewelry may be economical, however if it has no useful use, then it is not worth the expense. Eventually, the value of something must be figured out by its effectiveness, not by the amount of cash you are willing to pay for it.
