Not sure how much money that is, but I would start a “quiet landscaping” company that used reel mowers instead of gas mowers, rakes instead of leaf blowers, and I would undercut every landscaping company in my town just to promote the idea of a quiet neighborhood.

Not tell anyone and see how little work I can do at work before they fire me. I bet I could even get promoted.

Tell my wife I now have “fuck you money”, and then fuck her lots because she could quit her shitty stressful job and have energy again.

I would buy as much land as I could. Build myself a reasonable house and a load of barns. I have always wanted to run a farm animal sanctuary that takes in abused and unwanted farm friends. Then I would spend the rest of my days laughing at goats and cows and chickens being derpy. That and maybe take a nice vacation to the beach once in a while.

Buy off all the politicians and have them implement policies that will benefit the working class. Invest heavily in renewable energy sources and public transportation. Buy all the comic books.

Order a pizza, don’t want to make big decisions on an empty stomach

probably spend it on a bunch of landscaping for my parents yard to turn it into a “no lawn” (I fking hate mowing the lawn)

I’d do what Mark Cuban did with his Cost Plus Drug Company, which sells everything on it at cost + 15%, but for other essential products as well. I’d open up all types of stores that sell necessities - petrol, groceries, medication, plants, technology items, books, etc - at cost + whatever the lowest margin mark up I could get away with. The goal would be to drive prices down everywhere, not just at my stores. I’d also spend big on lobbying/campaigning for better legislation and regulation around essential goods and services.

Low cost public housing would be another area. Buying up land to build low cost housing estates with all the facilities and amenities needed.

Obviously it goes without saying I’d set up everyone of my family and close friends for life too.

I would try to ease the life of everyone around me.

I probably wouldn’t quit my job because I like it. I probably wouldn’t even tell many people I had that much money. My only debt is my mortgage so that would be gone. I’d probably buy a better house with an actual yard. Sell this house to my roommate for dirt cheap. (There’s no way he’d just take it)

Probably do some lying that my brother won some kind of raffle and give him a bunch of racecar parts. Shit maybe even sponsor a race team or two, gotta get the young kids back in the sport as all the old guys retire.

I’d probably buy some land in another area, give myself a vacation house. But this wouldn’t be immediate. Probably get a new car, mines pretty old. Build a greenhouse on my new property, have way too many rescue animals. Maybe even run a small rescue.

All this is assuming I’ve already set myself up for retirement and I’m good to go with everything else.

Assuming “fuck you” money is along the lines of being able to give away money without feeling a hit, I think it would be very interesting to use the money to donate to small open source projects to help them grow and expand with new features and resources.

Massive underground dwelling. Not sure why, but that was my first thought.

Buy a nice home, upgrade it to my liking (CAT6 to all parts of it, solar panels/energy storage/network cabinet/make it watertight and safe for the next 50 years), buy a shitty looking van with a petrol powered pressure washer and indemnity insurance and spend my spare time going around cleaning paths and monuments etc. in my local area.

Have a nap. Phone off, door locked, for as long as I want level nap.

I’d pay off all my debts, put away enough to be able to quit my job without losing any income, and give the rest away. I already have everything I want and need, the move now is to get rid of shit I don’t want.
