If I won the lottery,what would I do?

If I won the lottery,I will give it to my mom, my dad and my grandma or buy something they want. Then,I will pay for traveling because i think it's worth to pay. When we go to travel we will experience many things that we've never done before moreover i think the world is so wide and has many wonderful things that are waiting for us to visit, so i want to pay my money for this one as well. Even though i want to spend my money for the things i want but i want to save it for the future as well because we can predict the future. Therefore i want to be sure that i won't get a trouble in the future.
