Procrastination is rooted in emotion. It is really a fear of some other emotion. You don't want to confront the emotion that you will feel upon beginning a certain task. Will it make you feel unorganized, inadequate, guilty, foolish. You might fear the shame of having procrastinated in the first place. Maybe you dread the frustration of doing something tedious and dull. Maybe the reactions of someone else when you do something that needs to be done.
So it might work to give a name to the emotion you are afraid of facing. Maybe you don't want to face resuming a project you began and left in a chaotic state. Once you know what emotion you are dreading, then you can ask yourself whether it is worth it to face the emotion in question. You might decide that no, this emotion is to scary to face.
