Cleanliness defines the personality of the person. The best example of cleanliness at the office is your desk, so you need to maintain it. Keep as minimum things as possible on the desk. You can have a pen stand, the monitor, a couple of important files if necessary, and feng shui plants for the office desk. Apart from these, everything must be kept in a separate space.
To keep your office desk clean, use a Feng Shui office L-shaped desk. This, in turn, will provide ample space to keep your belongings, and it will look clean as well. Further, if you are using an office cubicle, use bookshelves to keep your important documents and files.
