Just think about whatever you have your mind on and just keep thinking about it until you see that its pointless and you know everything about it, if its not working just look up stuff about that subject ( if its **** watch some but do it in a incognito window(don't get caught)).
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.
