I'm going to get into this once, and then hope it takes on a life of its own. I believe it is important to put this down in words; how not to suck at things. Precision, concision, vision, decision. This is like asking "is this measurable, is this actionable?" But this is easier, I have found.
When you describe a thing, are you accurate? Are your facts correct?
Have you used ten words where five are required? Is your argument more complete when you say less?
Do you have a clear and compelling message?
Are you able to act on the information available?
