Given this much thought over the years and honselty I'd give myself a quality life, but keep it fairly quiet.
I'm not someone who could live a lavish life, just few odds and ends to keep me happy and that's all I need.
So save whatever is the best amount to set me up for life, sort out a few friends and family because who wouldn't.
First thing would be to sort out the friends/family then bugger off around the world, taking in everything really see the world, and figure out where I'd like to live.
Then 2-3 cars, one definitely being the new tesla roadster, then a big suv and after a nice bimmer or merc.
No mansion because well that's just daft, just a big house with a few rooms, big garage fully loaded with a pit, hoist and the usual.
Arcade room with everything from the 70s and 80s.
And that's it, oh and a Nikon D850 with all the gear I fancy, love trekking so love to have that with me when I bugger off.
