Are you asking if some of the principles were already automatic to us when we first started?

If it is the first, then I will say that probably nothing was automatic, because it was all new to how I done things, and I had to put in effort to learn those new skills.
If you were hoping that you could read the GTD book and just automatically have GTD down pat, without effort, and without having to go through the learning process, then that is just not a realistic expectation.
However, if it is the second, then I have been practicing GTD for about 5 1/2 years now and what I find is automatic for me are, checking my calendar, then next actions lists at the beginning of the day, and my context lists throughout the day, the 2 minute rule (that was the easiest and quickest) and the weekly review.
For others things, I still have to remind myself, and am still working on are things like emptying my email inboxes (I don't always check my email everyday) using my tickler folder, and clarifying/managing/reviewing the perspective levels which you learn about in Making it all work.
