There is not a greater challenge than to love those different than ourselves. But to not love generates the opposite characteristic… Hate.  C.S Lewis captures the end of this cycle so well in Mere Christianity. 

The Germans, perhaps, at first ill-treated the Jews because they hated them: afterwards they hated them much more because they had ill-treated them. The more cruel you are, the more you will hate; and the more you hate, the more cruel you will become—and so on in a vicious circle for ever. 

Good and evil both increase at compound interest. That is why the little decisions you and I make every day are of such infinite importance. The smallest good act today is the capture of a strategic point from which, a few months later, you may be able to go on to victories you never dreamed of.

 What drives your compounding interest? Love or Hate?
