How Does A Rebel Get Anything Done?

I love classifying things, including people. (Remember THIS joke?) Lately I have been thinking about the four personality types presented by Gretchen Rubin in her latest book: Upholder, Questioner, Obliger, and Rebel. I particularly like that there is a corresponding Venn diagram and that the types exist on a simple x-y axis.

The classification is in regards to how someone responds to rules, both those set by others and those set internally. Rubin starts to outline her theory in THIS blog post. Her definition of rules or expectations is very broad: Looking at people's response to outer rules, like laws, traffic signs, work deadlines, requests from friends, doctors' advice, and their response to inner rules, like personal resolutions, goals for self-improvement, or working on a self-generated project. Luckily she put together a QUIZ to help determine which type you might be - I didn't even have to take it to know that I am a Questioner. (I have to understand the reasoning behind an expectation, and agree with it, before I follow along.)

What confuses me though is how does the Rebel type get anything done? Basically as soon as something is a rule or expectation they become repulsed by it. Rubin does suggest that it is the smallest category. What are you?
