The value is always in the eye of the beholder. What is worthless to one person may be very important to someone else.
“Were I a king, I could command content;
Were I obscure, hidden should be my cares;
Or were I dead, no cares should me torment,
Nor hopes, nor hates, nor loves, nor griefs, nor fears.
A doubtful choice, of these three which to crave,
A kingdom, or a cottage, or a grave.”
Edward de Vere | 17th Earl of Oxford
