A stalled project is usually one of a handful of problems that feel alike from the inside, and their repairs run in different directions. Find the kind first, then the repair.

What kind of stuck is this?

What it looks like The kind First move
You know the next task and keep tidying everything around it Fear Do it badly, in one session, and let the result be rough
You open the project and cannot tell where to begin Too big Break the next task into pieces of twenty minutes each, and do the first
You cannot say what the project is for any more The shape is lost Reread the Project brief and rewrite the finish line in one sentence
Every session goes on fixing what is already done Polishing New work only this session; write the fixes down as Later tasks
The fix you found means redoing a large part of the work The expensive fix Write it down with a cheaper version, and carry on as though it were made
Another project keeps pulling at you Two projects in one Add the other one to Projects as Considering, and return to this one
Flat at the desk and away from it Depletion Fifteen minutes or a session note, then stop. File nothing as failure
Back after a gap, and the project is cold A gap Coming back, below

If two fit, choose the one you would least like it to be. One condition is no stall at all: if the project keeps surfacing while you are doing other things, it is incubating. Put what surfaces in the Inbox, and let it come.
