Awesome! A Cornell essay. Go you!
Describe your intellectual interests, their evolution, and what makes them exciting to you.
I don't feel that you describe the evolution of your interest for history very well.
You write about how you look at history but not how you started liking it. You do have one example about how the mayan video made you like to study history but you never state why this is.
These are my intellectual interests: studying history, and looking for things that can be connected to today.
I would say that a branch of history is, in fact, connecting it to today.
My love of reading and thinking about different ways of doing things translated naturally into an interest in the past and how people used to do things.
Quite broad. Especially since you give no examples of this throughout your essay.
Ever since, I have loved to learn about how people used to live; what they used to eat, what they used to build, and what they used to do for fun.
Why?
All the questions you ask in your body paragraph are, no doubt, already answered. I, for one, know why Japanese people fought so ruthlessly.
After reading this I do understand your love of history but I do not understand how you love history enough to pursue it as a career.
Good luck
