You sound pretty similar to me.

hwell: One of the confusing things in my type order was/is that my Te and Ne seem to be the most active in general, while those functions that should be accompanying (Ti and Ni) aren't so much (sometimes even ranking below Si). I'm not that extroverted, either, even though extroversion is supposed to be determined by the dominant function.
I wouldn't say that feeling driven to get things done is necessarily a different function taking over, though. (My Te is dominant pretty continuously, and yet I procrastinate plenty.) It might not affect precisely how you think; if it did, you should detect a bit of difference in your common reasoning processes. When in doubt, I'd go with your relaxed state as the standard.
