Story behind my topic choice

As a young high schooler, I have learned the English language is the hardest to learn. So this made me start thinking about how modern American literature was just a couple of yeas ago. It made all type of questions go through my head. So many like is everything still the same, who made the rule? How do you even come upnwith the rules and even how was it so many questions came about in my head. My head felt likeba train had hit me with all these questions and no answers. I also wondered when my great grandmother and grandfather were in high school did they have the same standards we have now, or is American literature changed over so many years.
