determine the income from the real esate. find some beautiful new idea. Invest in that. It will be some great new concept that will help the people of the world and provide you a perminant income.
from that you invest. and then, some day, when you are old, you take a small part of that and find a great artist who works in gold and commission a modest little sculpture or memorial thing . . . and have that crafted as a memorial item so that in a thousand years someone will see it and say 'huh, guy with realestate who invested in a good idea's memorial gold trinket thing.'
and then go get a coffee and walk amoung the hilltops and fall in love.
