At one point in our lives, we had to live our lives in a routinely manner. I'm sure it happens/happened to you whether you are a student, a mother, a worker--anyone. At one point in our lives, these people became bored of their lives for lack of excitement, lack of change of environment, and the like.
For example, homes are supposed to be the refuge of people after a long day of hard work. Homes are, well, to be the havens of these people where they could rest and all. However, probably due to the globalization, homes are turned into home offices. The house becomes the extension of the workplace. All you need are cubicles and voila! you now have a convincingly looking office inside your 'haven'.
While it is not bad (oh not at all) to convert your house into a large home office (but it would be better if you won't, but that is just impossible, right?), at least add some style and create some differences between your house and your office, appearance-wise. Putting up some decors will create a sense of "homey-ness".
For instance, why settle for ordinary formal-looking telephones when you can have these cute Mickey-Mouse designed ones? Well, who didn't love Mickey Mouse? I'm sure we all did. Why settle for white lights when you can have disco lights? Why settle for the sounds of nonstop typing on your keyboard when you can have the stereo on, playing the music you want as much as you want?
It's your home. Don't let the norms of your office control the way your house will look like. You're in control.
