The real work that we do does not reside permanently within any one activity. It is the attention and presence that we apply to the activity that makes it Work.
In the beginning, it may be hard not to be attached to the activity you have been "Working" through. You may even suffer temporarily from the delusion that there is no other thing to do as "Work".
For example if you have been "Working" by operating a truffle shop you might briefly be convinced that "The Great Work" is making truffles. You might not want to bother with doing anything else, like painting pictures, dancing, or reading to the blind, because after all you only want to do "The Great Work" and that means making truffles.
But the fact is that the more activities you engage in with a "Work" attitude the better.
Having various ways to work helps ensure the continuation of your Work.
If one project is inhibited for some reason it will not stop you from doing "The Work" because you have been doing it in multiple expressions. In this way, the special something you have been striving to cultivate will continue to thrive despite a disruption in one of its apparent forms.
Like ivy, hackers, or terrorists, there will be no one head or root to your Work, making it difficult for anything to impede it entirely.
Where working with another is concerned this is very useful in the sense that by maintaining multiple projects together you are creating multiple points of contact. If for some reason the contact between the two of you is broken in one "cell" there are other "cells" in which the contact may be maintained.
