Once you remodel a house, you see how the plumbing, electrical, insulation, heating/air, etc., work together to create a “home.” There’s no mysticism anymore; you see it like a contractor would.
The same is true for cars and brain surgery.
Part of the work of being a professional is demystifying the world of your expertise for everyone else. And if your clients doesn’t want to learn how to change the oil, it will continue to feel mystical to those who need their problem solved.
