One will often find that they trait they least like to see expressed in others is truly their surpressed weakness in themselves.
A trait I have recently not liked at all in another individual has been greed. They are motivated by Greed and it disgusts me. Then I ask myself, why does this action disgust me so.
and I ponder that perhaps it is the reflection of mySELF in that act that I do not like to view.
and I ask Greed, have I truly moved past you?
to raise the question is a good step...
