You win the USA Power ball for $1,000,000,000 what do you buy first?

i think the first thing i would buy, is a long, beautiful vacation on a lonley beach, or island maybe, whith my family. Chilling, forgeting about all the stressing time i have making some money. And after this i would buy an house on a lonley beach, or island maybe, family, chilling, forgeting...... LOL.
