I didn't Aussies used the expression "out of left field"! It's a baseball expression.....I didn't baseball was too big there........with the love of cricket and all.......but I try not to look for too many answers......I may not like what I find!
It means the search will take all your energy and you may forget the question as in Hitchhikers Guide to the galaxy where the computer took foreverr to say the answer is 42 and then asked the real question which is what was the question.
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.
