A horse with bags of mail (information)

Today in a simple conversation, I grew again.  I was talking with a CODE model coach about (an old concept that I used to relate to) of feeling like a dog being weighted down as I carried what others or I thought that I could or should carry.  As the conversation evolved and we got to the point of talking about where we are at now in our lives the image transformed to a, “mail horse”.  I am sure that there is a proper phrase for this metaphor, I see the image of The Pony Express and who cares.  The image is so freeing.  A horse, so powerful and majestic carrying, light, information filled letters from place to place.  This image has stayed with me for the rest of today
