I love your questions Faisal. One is not born with empathy it has to be taught. Put yourself in someone else's shoes ask yourself how you would feel.
That's empathy. I try and teach my children in this manner. Something happens to someone and we discuss how that person might feel and how they would feel if that happened to them.
Try remembering a situation where you and someone else had a different opinion. Then when you have that memory see it through your own eyes and remember what you thought and what you felt. Then 'float' into the other person's body and see you and the situation through their eyes and notice what different thoughts and feelings you have.It's a matter of practice.
Understand the other persons circumstances and ask yourself how you would act under the same circumstances. For example, a parent can always ask himself or herself how they would behave at the same age as their child. Often children are punished due to lack of empathy by parents.
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.
