If I'm a millionaire

I read a news that a man who won lottery and become a millionaire in a night. We were gossiping about this topic during our lunch and every one of us started to dream if we are the man. Some said, to travel around the world with partial of money and keep the rest of it in bank. While some said to quit the job and start to live with no worry. And I said, they all are silly by simply spend on the money. I would rather go for investment like either investing in gold or to buy gold coins at a trustworthy bureau, which I can double up my money. Don’t you agree that?
