As Mark says, raising the priority of one thing is the same as decreasing the priority of everything else.
What if, instead of raising a priority of a few and lowering the priority of all the rest, we reversed it: Lower the priority of a few, thereby raising the priority of everything else.
New Question:
How disappointed would I be if I did not make progress on this project in the next hour? Few hours? Day?
If not very, then lower the priority. Somehow mark which lines are, for now, of lower priority. Use system of your choice on the remaining lines.
Dot (or star) most lines, since you don't have very many low-priority things on the list, right? (If too many things don't get a dot, time for an audit.)
