First - please be sure to remove all coordination from your home. Recent studies have shown that balancing the cloth of your living room upholstery to the window and floor treatments can spark sensations of appreciation and pleasure in household members and guests. It is therefore critical for the practicing conformist to remove all hints of matching or complimentary designs from his or her household.
After dealing with those messy matching issues, be sure to walk through the rest of the interior searching for original art pieces such as paintings, sculpture and folk art. An interior which includes originality in their wall décor would evoke a sense of personality and interest in guest of the home, and it should also be noted that these guests might then find themselves assuming the "good taste" of their host. That defeats the purpose.
To the delight of the true conformist, many interior designs are stagnating into set themes. But you must take this a step further, and be certain that no new design or decorating ideas
are found throughout your home. Do not allow any inspiration to come from, say, your favorite books, magazines, or movies. In fact, stop using any of things for entertainment. They will only lead to further thought "outside the box."
Use your head people. Actually, do not use it at all, because that is the best way to avoid any originality or sensationalism in any interior design ideas. It is, unfortunately, too easy to find simple inspiration throughout your daily life. It is imperative that you do not write any of these ideas down, and then you will have a chance to forget your initial reaction and idea and move along in your simple, easy, and non-threatening little life.
