I was speaking with Jay last night. We got deviated from regular chit chat to wealth. The summery was short in simple: what will I do with 100 castles when in the end I have to sleep in one each night.
The difference between a poor and a millionaire boils down to our needs and how we see our world. A poor can be happy, healthy and a millionaire can be sick, vulnerable.
The castle is our mind, our thoughts.
