The point is to look back on memories in your past and remind you what a great or sad time or whatever time you had in your life. I put a letter to my future self and asked questions about my future self and left blanks for me to answer when I look back on it. Also I put my current favorite thing and some current pictures of events that happened:).
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.
