In short, what I want out of life is largely not material things, but just a nice place to exist and pursue my interests.
I realize, of course, that nothing about this is particularly radical, I don't expect this comment to blow anyone's mind. By my estimate a cool 8-10 million would be more than sufficient for me to have basically everything I ever wanted - i.e. buy the aforementioned nice home and then live comfortably off the returns for the rest of my days.
If any recently minted tech billionaires reading this would like to donate to the cause of me fucking off from society to the woods, feel free to shoot me an email ;)
