Relationships are not a battle of the egos

And everyone who comes into our lives changes us in some way. If we are no different at the end of a friendship or relationship or even professional relationship than we were when we started, we're doing it wrong.

"'The words 'love' and 'change' used in the same sentence carries a negative connotation for most people.  'What do I look like changing for somebody else?!'  is the question some people ask.  If I had to give an answer, I would say 'You look like love.'" --Euphoric Ears
