Decorate a Small Office at Work

No one wants their area to look boring. Having a nicely decorated office can improve the efficiency of your work.

Steps

Put anything not too personal. However, nice pictures of your family, pets, and friends can cheer up any area.
Consider giving your computer or laptop a nice, bright background.
Consider putting lamps on your desk. If you have enough room and a free plug, a colorful lamp gives you not only more light, but also more color.
Find some colorful organizing equipment. You can find nice, non-childish paperweights, files, boxes, and tacks that can go anywhere in your area.
Look nice when you come to work! A happy, well-groomed person sitting in the desk-space can always make your area look nice.
Get a mirror of whatever size. It makes the space look bigger and reflects whatever other colorful items you have.

Nothing inappropriate. Keep the pictures classy. No one wants to see it, and its not a good way to keep the job you have.
Don't throw things in your office space that just clutters the area and makes it harder for you to work.
If your boss or someone else warns you that your display is attracting negative attention, take it down, but only if the person telling you is reputable.
Don't go too childish.
