If I could be anything, without needing an education or money troubles, I would love to see the world and help those less fortunate than us. Being young is an excellent time to see the world because that is when you have the energy to walk around and see it. Not only that but you can make new friends from all across the world and make opportunities in other countries.
It would change the world by allowing people to have the necessities that everyone needs: education, food, a place to stay. It will also allow other countries to see that, what they hear and see in the news, is not completely true.
