The medium is the message (one layman’s understanding):

I believe he was referring to the context that one appears in, the surroundings, the clothes, the projected attitude...

that your medium (that you are immersed in, what you paint your story with) is your message.

Dress and act as a good doctor...says, “This is a good doctor” and you don’t have to say it yourself.

Oil paint is a medium for expressing art on canvass. Watercolor is another medium. The medium is the message...
means that your choices of style around you tell the customer what the message is before you open your mouth to explain it.

yeah, well, perhaps. I think McCluhan probably had that figured out in the second grade.

It's cliche now.

What's not cliche is how the media tells you things which say far more about the media than the things they purport to tell you about; the message being, not the subject, but the media. Or the 'medium' if you prefer.

That's the irony: that the message is about the messenger.
