I have worked for 2 lots of multi millionaires, and they may or may have not been typical.....
Neither of them were happy. Paranoid, touchy, jealous, petty, power crazed and quite weak. They owned multiple properties throughout the world and plenty of nice cars, country estates etc. There was ALWAYS something going wrong. The more you have, the more chance for it to break I suppose. It made me appreciate my fairly average existance.
They both ran shoots and would invite friends. You think MAMILs with blingy bikes are tossers....?
