What would be the most important thing for future historians to consider when researching the past?

Hi, Joshua! That's a terrific question -- and that's what all good historians start with: Good questions about the past that they want to answer, mostly because no one else yet has. That question can be about how people lived, or what they thought, or why they did some of the crazy, noble, or just weird things they did. The questions that interest you will determine what kind of historian you'll be. If you're interested in how people related to each other, than you might become a social historian. If you're interested in how people thought about their government, you might become a political historian. I was interested in why colonial Americans wanted independence from Great Britain, so I became a historian of the American Revolution (and then an adviser to C-SPAN and Disney). If you want to become a Smithsonian curator, then your questions might revolve around objects, what we call "material culture" (or, if someone drops that object and it breaks into pieces and gets buried, then we call it "archaeology"), because that's their biggest responsibility -- taking care of America's most historically valuable objects. But there are many ways to do history. The key is to find out what interests you so much that you'll never get tired of researching, reading, writing, and talking to other people about it, especially because it takes a lot of extra education to get the degree you'll need to get that kind of job (It took me six years *after* college to become a doctor [Ph.D.], and that was relatively quick).
