First of all, get a doggo friendo or friendos to keep me company.
Second of all gather enough food, fuel, guns and information about the easiest way to generate energy for a single household. Maybe just go with solar panels or something.
Spend entire life playing with doggos, watching movies, making music, playing vidya and reading books.
Kill myself whenever I like it.
Also I'd like to leave some sort of written history of all humanity so that ayy lmaos may find it in the future. Probably also make a video visually showing the meaning of very single word, so that they have easier time understanding.
