I know the feeling! The temptation of getting generating any sort of money resembling a decent profit off on an old piece of property is something that I've experienced many times- it hasn't been until my more recent years when I've understood the gravity of my actions from a much wider perspective. Additionally; to think that my parents never forced me to sell or throw away the majority of my childhood property like their society instilled into them, and yet I still sold so many precious things of my own volition! Some things truly are priceless (and not in the collector's sense).
