If you had a net worth of $20 billion, what would you do?

If I have that much money, I would give back to the community, help my family, travel, shop, buy a nice house in another state, pay off college debts and put it all away in the bank. If I want to start a business, I can save to invest to make more money.
Imagine having $20,000,000,000. You will be set for the rest of your life unless you get bankrupted. Just saying. Then again you’ll have to watch out for people that only want to be your friend or only want to be in your life because you’re rich because they can take advantage of you.
