You still have some time left to get ready for university level studies, so maybe it is time to start your planning of your university education so you can go to graduate school and get a Ph. D and do research? I assume you are smart enough to do that.
Also You might have some entrance exams to take, so you still have time to study a bit more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
