GTD and ongoing "projects"

Just today a guy who rasies his own support for ministry asked me:

Hi Mate,
As you know I have to visit churches... and i need to always have this as a kinda 'to do' but its ugly in my projects list... coz its never ending... where would you put such a project? is it a checklist? i.e. i put the churches on the check list and revise it from time to time?

My answer is that this is not really a "project" but an "area of responsibility". This area of responsibility then regularly spawns projects, like killer aliens spawn little facehugger crab things.

Mentoring someone or working on your Hebrew would also fit in this category.
