This is 1.3 BILLION. It seems to me that all of the things you are mentioning (other than Fermion's space ship) could be bought with 100 million or less.
I can't think of anything that expensive for myself either, because the buying power of that much money is beyond my wildest imagination.
Besides, I don't really want a spaceship.
The only solution is to give it all away. Then people would tell you how great you are for doing that, when really you aren't a saint but just don't have any other choice, due to lack of ideas. That would be so unsettling. I'd feel like a complete phony or fraud.
It would probably be better for me to just leave well enough alone, and maybe just throw away that winning ticket and call it a night.
