When decorating a home office, start with the basics. The desk, filing cabinet, printer, fax machine, and all other pertinent work space materials should be the focus of the room. By placing the desk where work space will be optimized (such as in front of a window for some and away from the window for others) the room can be created to draw away from the desk. From there, creative inspiration becomes the key focus. This isn't just for those who are in creative fields. Creative inspiration works just as well for the business person as it does the writer, the inspiration is different. After all, we all work for a goal. By interweaving that goal into our workspace, we can create more efficient places to work because we've given ourselves a psychological advantage by surrounding our psyche with décor which motivates us.
To draw the room together as more than just a collage of inspiration, home office décor should also correspond with each other. If you choose a classic theme and add to the décor with classic nautical pieces, the entire room should reflect the same theme. Using one piece of classic nautical and one piece of new age and so on only creates confusion and in-cohesiveness, which psychologically detracts from the room's inspiration. Additionally, a home office is used for peaceful working on projects that are not motivated by monetary gain, such as personal journaling, reading, and self improvement. A chaotic home office is really not conducive to this sort of creative energy.
