You can boost your productivity if you have a polished and clean workplace. Office organizing and removing clutter will get rid of those anxious feelings and allow you to focus on your work rather than cleaning.
To stop clutter from piling up, you should consider having organizational systems. This is not only for office or home organizing but when your downsizing, too. If all your things in the office have a home, you will feel better, calmer, and more prepared to take on any project.
