I keep a running list of papers to write on my whiteboard.
This list currently has 15 entries.
Two of these have been accepted for publication this year but not yet taken off my list because it is nice to see them there.
Another was submitted, rejected, and is waiting rewriting.
Two have nearly complete manuscripts written and have been sent to colleagues for comments.
Five more are actively being worked on by me or co-authors and will hopefully be finished by the end of the year.
Four others are collaborations that are currently not moving. One of those is a project died for some specific reasons (like the data couldn't answer the question) and I just haven't entirely decided what to do about it. The others are things that neither I nor my collaborators are currently prioritizing that I hope we will get back to.
Finally, I have one project on my list that I want to write, but I don't even know exactly what data I need or the approach I want to take. I just know it is an important paper to write.
There are roughly a million other ideas I could put on my list, but I'm having a moratorium. I have decided I am not allowed to start on anything else until my list gets a lot shorter. As I have mentioned, I am applying for jobs, and I'd like to have most of this backlog cleared up before I go.
