As you read other works, notice how the author seems to disappear, and there is a "voice" in your head, telling you a story. The voice of the narrator can sound folksy or stuffy, educated or gossipy or friendly. I think O.
Henry sounds pretty snide. Voice is switched up in "Wuthering Heights" between the traveler and that of the housekeeper. Notice Hemingway often has a conversation drive the action, and each character in the conversation speaks with a different "voice."
If you look for it, you will be better able to imitate it in your writing.
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.
