What should I do with all this money?

After several years, I decided to visit one of my summer houses on the beach and found a box of money that I forgot I left there in-case of a rainy day. There nothing that I can think of that I want and do not already have. What should I do with $35 million? I don not want to just give it away, that would wasteful. I am curious, what do you do with your left over millions?
