What costs little is little esteemed

We tend to value things by the amount we pay for them, which is not always their true worth. The same article may cost twice as much in the fashionable store as it does in the little shop round the corner, yet we try to keep up with the Joneses by buying it at the store.

The same applies to other thing. For example, good health costs nothing, yet we do not value it until we have ceased to enjoy it.
