I'm guessing that you live in one of the countries that Google puts the requirement on of having a site up for six months before applying. They do that so that they can sort out the bad sites from the good ones in places where they get way too many bad ones.
I have my own website and used AdSense for several years before I started here.
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.
