As I've mentioned before I was a general entrepreneur ....anything that made money.
Entrepreneur? (I know pushpills is always interested in the details LOL)
At various times had interests in a Classic Car garage , pubs , clubs , restaurants , car parks , caravan park , scrap metal yard ....you name it lol.
Best "earners" were...
Property developing in the UK...buy a house tart it up sell it /divide it into flats sell them.Buy a house with sitting tennants.Charm the tenants out..sell it
My first job sorta related to computers was persuading pubs in Britain to install our game machines on a partnership basis. HUGE money in that.
It does give you a half assed background in various businesses and it is always fun
