This feels like an over-simplification. Life doesn't fit into 4 quadrants, and the only thing models are guaranteed to do is be inaccurate. "One thing" and "well" are fundamentally subjective and based on a particular use-case. You have to focus on the problem(s) you're solving, and be disciplined about the scope of the problem(s) you're solving.

My model of gmail is gmail. This model is 100% accurate.

I don't mean this negatively, but I don't understand what point you're making...
