Imagine you could ask any one person in the world any one question. That person would have to answer that question with absolute honesty. Not just in the letter, but the spirit. Nothing ambiguous, no confusing speech or cherry picking, just a real actual answer.
Who would you ask, and what would the question be? Keep in mind that you must accept the answer, even if that answer ends up being "I do not know."
Ive been trying to think of my question for a few years now. I still can't decide.
