Allen writes about Priorities...he also mentions they're not set in stone...but also shifting, based on due dates, context, energy and focus.

Priorities? Take a look at your (context) list. You know RIGHT AWAY if something is important. REALLY important.

Do you have a 'too long of a list' in a given context?
Try limiting it to the "Next Available" action, rather than every action.
