Well, I guess I would now have enough money to have my own stud farm and string of racehorses. Hey, I might even buy Ballydoyle!!
I would be able to buy some nice presents for some special people; donate a nice sum to two parishes - the parish where I live, and the parish where I grew up, both of which are doing some building/restoration work at the moment; buy a nice new car (BMW probably?).
Short term, I would probably do nothing; just put in into the bank and wait a couple of months while doing some research and making investment decisions.
Will it change my life? To an extent, yes, and that is ultimately why lotteries exist and what they trade on. And before you ask, No, I do not play the Euro Millions or the Lotto or any of the scratch card games. The odds are bad value!
But what would I do about all the begging letters?
Simple - I would just keep sending them!
