I am rich and have no idea what to do

God, we use to have a street full of people running unprofitable stores. Some were deep in debt making the dream a reality.

Why not a functional bookshop? You don't need money, you need to work on the plan(s). How do museums work? Where is the crude draft for the book?

I had a chat with a guy once who had a laundry list of things he wanted to accomplish but had convinced himself non of it was possible without money. About 1/3 of the list were things one could just go do right now.I think a hundred life times worth of stuff It was mostly helping people in need. One could definitely not help anyone and convince the self it is because it always costs money????

Some non profit here was selling unwanted books for 1-2 euro. I spend an hour or so typing titles on my phone mostly stuff published long ago and bought a whole stack of 200+ euro books. I haven't looked at them and didn't try to sell any but I'm sure it was money well spend for an hour of fun.

You don't need a machine gun, fight with your bare hands.

There is "Purpose" and "purpose".

One is some grandiose ill-defined thing. The other is housework.

I am certainly in the housework side right now with two kids under 5.

I am a dad, but I still derive quite a lot of identity from what I do for work. If anything, now that I am meeting more parents from nursery & school etc it feels it is almost more important for me now to be able to implicitly assert status through my work/wealth/house-in-desireable-location/car/etc than it was before kids.

I assumed those sort of feelings would dissolve with kids ("Purpose") but if anything the kids have magnified them. Potentially I am just a shallow prick, but I wonder if it is a "provider instinct" thing or perhaps just mini dopamine hits from feeling like I've got something desirable and meeting these other parents just reasserts that over and over.

Right. There's no rule that if you get a hold of $XX million that you need to keep it. I'd argue, in fact, that there's a pretty good case you're obligated to give most of it away; you can keep single-digit millions and have total financial security for all practical purposes while sacrificing only a few luxuries that, as the author of this essay appears to have noticed, won't actually give your life meaning. Meanwhile, each $1M donated to insecticide-treated bednets (for one well-quantified example) could save hundreds of lives: https://www.givewell.org/charities/amf#What_do_you_get_for_y...

If there's a moral case for keeping the cash, it's the leverage it could provide to do something that (at least has a chance of being) even bigger. But few are the people who have legitimate reason to believe the expected value calculation comes out positively. People who feel directionless or jump on the latest Elon thing on a whim seem especially unlikely to be among those few.

(I'm not going to provide documentation, so take this for what little it's worth, but I myself gave away the majority of the several million I received for being a sufficiently early employee at the right startup. And I do not regret it.)

I think if you are doing things just to keep yourself busy or self-focused stuff like learning a language or playing an instrument, you will eventually hit the wall of motivation created by lack of necessity when your financial needs are already met forever. Definitely do them to keep life interesting but don't expect that much from these activities (unless you are like crazy passionate about any of them, in which case, congratulations, you found your true purpose).

I believe you'll need to have goals that involve improving lives of those that most need it. Of course it is more complicated than just that - there will be disappointments, betrayal and all other stuff that comes with getting other people involved but the key is to do it based on purpose, with a calm head, clear goal and less on fumes of emotion to manage such pitfalls better. You can let that emotion out when you see the unprivileged child you mentored succeed - I would wager that that moment will outweigh practically any joy you could feel from solely self focused achievements.
