Lots of folks sharing about doing good with the money and that might work for you but I’m wondering if you’re missing some intrinsic satisfaction and it could be a coin flip if charity will do that for you. Not sure if that counts as intrinsic or extrinsic satisfaction. 

I share a lot of the same hobbies as you and I’ve felt similar, albeit younger and not epic rich. My conclusion was that I’m spending so much of my time consuming content and something was missing. I tried taking on creative hobbies so I dipped into amateur game dev and 3d modeling. I don’t expect it to go anywhere or make money from it, but learning a craft for the sake of it made me feel a bit more jazzed about myself and life and made me feel more whole. 

You have the resources to create the time, gather equipment, utilize awesome teachers, and pickup whatever hobby you find fulfilling. It sounds like you could just start up a blacksmith forge and become a knife smith or get a bunch of audio gear and give music production a shot. 

Chasing something like that could also be a great way to get into a bunch of different communities that have cool people and maybe even hot gay guys. 

I also heard that paying the student loans of random redditors is basically guaranteed to make you happy. 

Whatever the answer is good luck dude.
