I have 43 top-level projects, 29 sequential and 14 parallel.

I agree that trustworthiness is an important aspect of a GTD system. It's what lets me not worry about whether I'm missing something important. To me that means spending a bit of time during daily inbox processing to set up any new projects correctly. I would also need to do that if projects were parallel by default.

On the other hand, the part of GTD that lets me move fluidly when in "doing" mode is that the set of actions is limited. I wonder if the sequential default encourages the development of this "focusing" habit. Thoughts?
