I don't worry about owing favors, but try to help anyone in true need.
I like to think of it as an equal exchange. What I do is very simple, if a person is angry, then I match them with the opposite emotion to try to brighten their day. If a person is happy, I try to meet those energy levels and keep them in their positive state of being.
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.
