Enough Is Enough

Too much desire is a fearsome thing;
It makes a villainy of what was good,
And so makes mockery of valuing
For how is value to be understood
When it can change when it has been obtained?
Since every wish is valued when it comes,
And so desire of want is thereby unrestrained,
How shall we make account of these strange sums
By which to add more value will make less
What came before it, and to take away
Is to make what was great increase? I guess
There's only one thing left for me to say,
Which is, there's one way out of this odd bind:
Look not only at quantity, but kind.
