I've heard that if you don't make the transition before the kids turn 4, you land up never being able to make the move. I'm not sure why this is - perhaps up until the age of 4 kids are able to adapt more easily, and it gets harder as they start school, create friendships and get used to life outside the home.
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.
