In the past I was Head Gardener on 2 private country estates. The first one was inherited wealth. The man had a 3,000 acre estate in Cambs, a London mansion, businesses all over the world, more flash cars than you could shake a stick at and a trophy blonde wife. Sounds good eh? There was a pile of anti depressants by his bed, he was usually having to fly off somewhere cos something had gone wrong somewhere, and he was always angry. One day I had to take him and family to Luton airport. 8yo daughter pipes up "daddy..." He replied "not now, in a minute" the little girl shot back, with venom "it's alwYs in a minute!"
The other lot had a 1,000 acre estate in Cambs, 3,000 acre estate in the borders, 1,000 acre estate in Italy,, 5 BIG London houses, a farm in Norfolk. He had an Audi A8 that just sat there, a Range Rover that he didn't like but had to have as his shooting mates would take the mick. His wife was desperately unhappy. These were self made people.
I could be really nasty and uncharitable about them, but I won't here. I think the common theme was that more stuff they had, the more chance there was of something going wrong, which seemed to be constant. They were constantly under the impression that people were trying to rip them off.
From where I sit, if I won £100M on the lottery I'd take it, but I'd be mindful of what I'd seen. Having enough, like I do is great, having way too much like them leads to problems and dissatisfaction.
