I had another thought. If you are trying to change your habits, I would consider cleaning out the room you sew in and then putting away everything but the one project you choose to work on. Out of sight is out of mind. Organize your WIP so that each is away in its own contained box/bag, not laying out where you can see it. When trying to change a habit, it can be important to change the environment to support the new workflow rather than relying on discipline alone!
