Steve's complete citation:
Going back to the electricity example. Imagine a battery. It has two terminals which are polar opposites of each other, one positive and one negative. If you hook the battery up to a circuit, electrons will flow in one direction, thereby creating a current. If you flip the battery around and hook it up the other way, you’ll reverse the flow of electrons through the wires, thereby creating an identical current in the opposite direction. (I’m trying to keep this analogy simple, so if you feel the need to out-nerd me by bringing up things like differential resistance, manifest a life.)
You nerd
While his battery example isn't the perfect one, as he said, he just wanted to do an analogy to make things simplier.
But your Fireworker and Stillworker ideas are very good and creative, i liked them. But i don't agree very much with them. Your Fireworker and Stillworker models are very similar to each other.
According to your model, a Fireworker
"exhibits large flows in both directions", while the Stillworker
"avoids the warp-and-woof of giving and taking".
So they are both
"neutral?
Its impossible to never give and never take, so a Stillworker would also give and take the same way a Fireworker does.
But i think there's place for one more type instead of just Darkworkers and Lightworkers, which would be the Neutralworker. A Neutralworker is quite like you described your two types which IMO are actually just one type.
But as steve said, 99% of people are Neutralworkers, because they havent polarized, so we go back to the initial dillema of either polarizing or not (advantages and disadvantages) which steve has already written about in his polarization and dark/lightworker articles.
