I am rich and have no idea what to do

Same situation, I truly empathise because it really does seem to take a lot of purpose out of everything. What I’ve found is that you need to replace money/salary/financial success optimisation (assuming you spent a lot of your life and energy to this point focused on these, much like I did) with something else totally unconnected with being measured in that way. For me, I am focused on proving myself as a guitarist in the local jazz and blues scene. These people have no idea how much money I have and wouldn’t give a shit if they did (I didn’t really change my lifestyle after getting lucky so it’s not obvious). So it’s an area I can be creative, grow, and still feel like I’m doing something. At the same time I’m doing part time consulting, mainly for people I worked with in the past who have started companies, just to scratch the tech itch. So far so good but I can’t say yet if it will stick. Maybe for you it’s art, music, going and getting another unrelated degree, or something along those lines? If you have more money than you know what to do with, fundraising and supporting good causes can be really rewarding. Both in terms of giving back something to your local community, and having really nice social elements to it.

One big piece of advice I have is to try to avoid letting others in your social network know exactly how successful you’ve been. Everyone starts wanting to pitch you their investment idea and it can burn down friendships when their ideas are bad. Being a VC to your friends is a path to sadness for everyone.

Therapy. Wealth and success is one of the most massive crutches there is. It can make it almost impossible to be truly in touch with your insecurities and pain because its simply too easy to hide in your victory. Your toughest challenge now is to, despite your wealth, find a way to contact the pain that drove you to your hunger for success. As the bible said, it's easier for a camel to get through the head of a needle than for a rich man to go to heaven. I interpret that metaphorically.

Sounds like a good time to engage a professional coach or therapist, if you haven't already. Particularly to deep dive on the questions asked at the end of the post. In my experience, I often stalemate these kinds of internal debates on my own, but having a second player in the mix got me out of the gridlock.

Opposite problem. I am tied to a corporate job, and I'd absolutely know how to use every second. No, really. Every second.
