GTD prioritizing revisited

[ero213]

I've been re-reading "Making It All Work" and came across this passage:

"The more direct between our actions and the most elevated horizon, the more it would be a priority--at least in substance. In other words, the more you know that the action you are taking is the best thing to be doing to fulfill your purpose, the higher its value to you will be."

Interesting. So if I'm looking through my list of next actions and one relates to my goals I'm more likely to pick that one? Of course, then there are the 3 limiting factors:

-Context
-Time available
-Energy

So the algorithm for figuring out what to do next would go like this something like this:

-Do I have control of over my context?
-How much time do I have?
-How much energy do I have?
-Of all my next actions, which one will advance my goals/vision/purpose?

Those are a lot of factors to consider but I believe it does fairly accurately represent our reality in any given moment.
