Influential. People like Albert Einstein or Thomas Edison are examples of influential people. They helped make many useful inventions which we use everyday now. I would love to be one of those two.
If you're rich, then there's basically nothing you can do. I enjoy doing what I love, as well as making a living off of it.
It depends being famous though. If I were someone like Justin Bieber, I wouldn't want to be famous. Sure, there are some fans out there, but a majority of people hate me. If it were someone else, like Steve Jobs, or Mark Zuckerberg, I would have many fans, but some people that wouldn't like me as well. It's a 50-50 chance.
