Are we talking about adaptability in terms of social interaction or physical changes in the environment? Either way, I'll offer my perspective.
I tend to follow the rules that I know so that I don't get in trouble in formal situations, but I often work my way around the rules that are not explicitly stated so that I can get away with shocking others. Of course, I also get into trouble for doing that which isn't explicitly stated in writing. So I tend to break morés.
In terms of my general environment, I need structure, control, and predictability. I do not like sudden changes, although I find I am able to adapt to them within a reasonable amount of time.
However, I am not a good self-starter, because I get addicted to the control I gain from having structure. That and I am addicted to the computer and the Internet. Any thoughts of actual changes I have hardly ever go beyond the conceptual stages because (A) I am either impatient with the details of making them a reality or (B) I give up on it because I get stuck in the details.
Personally, the description of the INTJ in Type Talk nails me in the head, especially since it recognizes that INTJs are often underachievers and not always good workers.
