What would you do with $10,000,000?

Put it with what I already have and carry on as normal I guess.

Spend some, share some, invest some. Move away from all the toxic people in my life and start enjoying it. Buy a van, set up a bed in the back and travel the country. Travel the world. Buy properties all over. Write a novel. Rescue some animals. Eat good food.

I'd buy a nice house with a pool and a hot tub but other than that I'd probably just hang out at the same stupid bars drinking and eating the same cheap beer and pizza.

I'd give $1M to charity and save the rest. I've never been the type of guy to spend money on things that aren't a necessity.

Build my dream house, with a pool and slides, a gravel tennis court, basketball and football field. A home cinema. A pool table. A playground for my nephews and nieces. All my favourite art on the walls, jack vettriano, edward hopper, beksinski paintings. A bar in the basement and by the pool. A collection of all the movies and tv series and comics I like. A couple of dodge challengers. I think this would cost about 10 million.

I would set up my own physics research lab in collaboration with a major university.

I would become much, much more reclusive than I already am. And that's really saying something, as I am quite reclusive already!

I would ... relax. It would be nice to not worry about finances in the future, and work has been iffy these past few years and low paying. If I had $10M, I'd seek financial advice, upgrade my life a little, spread a little around, and thank my lucky stars.
Btw, a really good professional NHL hockey player currently commands around $10M a year, far below what other star players make in other sports. Of approx 700 players, at least 34 who are signed makes $9.0M or more in salary in a year. That's out of the top 50 and at least one other guy will likely join them when the season starts.
