Your name or your health — which is closer to you? Your health or your possessions — which is worth more? To gain or to lose — which is more harmful?
Those with excessive desires incur great cost. Those who guard wealth surely suffer great loss.
To avoid disappointment, know what is sufficient. To avoid trouble, know when to stop. If you are able to do this, you will last a long time.
(from Tao Te Ching, verse 44, translation by Robert Brookes)
