“We tend to take every precaution to safeguard our material possessions because we know what they cost. But at the same time we neglect things which are much more precious because they don’t come with price tags attached: The real value of things like our eyesight or relationships or freedom can be hidden to us, because money is not changing hands.” — Peter D. Kaufman
