I was wondering if those who rigorously implement GTD in their work also have a clean work environment.

From your perspective, are they simply co-incidental, or does one support or cause the other?

I try to implement GTD (as far as I have been able to read thus far) but I have a somewhat messy apartment (though my office, where I do most of my work and receive students, is pristine).

I see an interesting parallel between those who say "I have a system that works" both for GTD and for a messy space.

Thoughts?
