Love no matter what. 
This is your greatest challenge, and few meet it.  Nevertheless, it is worth the effort.  So many do not even pay attention to what
they are feeling, yet if they were to do so, they would find that what propels
them to act as they do is the innate desire for love.  And then, in this state of greater awareness,
if they were to pay attention to others and send them love, they would find
more of the feelings they seek welling up inside.  Love more. 
It would change your world on a personal level and on a profound
level.  Love is the catalyst for
change.  Nothing else.
