If you could meet any one person, who would it be?

A talkative one, aren't you?

If I were to meet any one person, I'd differentiate between the current position I'm in due to that person's knowledge and what I'm currently wanting.

If I wanted to meet an actor, I'd go with Charlie Day, because he's a comedian, as well as an actor who looks at least somewhat humble.
If I wanted to learn about economics, I'd meet with Elon Musk and discuss company shares and how he got started with Tesla.
If I wanted to learn about physics due to occasional thoughts and ideas, I'd speak with Stephen Hawking because of his current theories.
