I use mostly electronic (reminders on the iPhone/iPad). In my @projects list is where I keep my project goals. In fact I try to word my projects on my lists as goals. If there is more to the goal or project description I'll use the notes section. Looks something like this:
@projects (this is the list header)
**Complete business analysis for xyz market event (the ** indicates I have notes attached)
NOTES SECTION: review market declines, sales force reallocation opportunities, budget reallocation
Hope that helps!
