For many, it doesn't last to the 10 year mark. You can be crazy in love with your partner and not "think about them all day". I've been married and the "think about them a lot" stage wore off after a while, but that didn't mean I didn't think about them at all during the day or look forward to seeing them after work.
Everyone's different though. I'm sure for some couples that stage you mention never goes away, for most it changes over time.
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.
