After 23+ years of working in various capacities, I would put myself pretty much at 5, but only because I know how much I don't know. I am successful because I recognize that EVERY box, network, installation, AND user is part of a completely unique ecosystem. An update, a new application, a "simple" HW change, can all tip the balance. I learn something new every day, and what I learn gets tucked into my brain, increasing the base of knowledge and building the integrity of the intuition--for what we do is as much art as science--I impose on each new problem. It is why I have been able to fix the unfixable.
All of that, and I am REALLY good at forming Google searches

That skill can make almost anyone look like a genius!
