Stop working? No, I'd start working and think about how I could make more out of it.
Buy some cars? Sure, can't hurt to have those.
buy an island? Possibly, I wouldn't want to spend everything at once, perhaps just a nice vacation house on an island.
Buy a jet ? I don't really see the point, I would always fly first class with the best airlines though.
Giving to poor people? Perhaps sponsor a local charity.
distribute to fam,friends? Not entirely sure to be honest, people would see me as someone who they can use for money and ask for loans. I don't think I'd like that.
Leaving your country? For sure. I'd want to travel everywhere.
