Is it too nebulous to say that getting that lump checked is a high priority item? That won't change.
Mow the lawn - medium priority. That won't change.
Read that self help book - low priority. That won't change.
If for some reason my friend tells me I just HAVE to read that self help book, I can raise the priority if I want to. But that's a decision that pretty clearly belongs in my GTD process. The whole point is to get concepts like priority all out there, on paper or in a database. Simply keeping that in your head, and having to think when you glance over that item "geez, didn't Jenny tell me to read that" defeats the whole purpose of GTD.
