Order and organization reflect aspects of personality and mood. How organized a person is depends on the individual. Order and organization are important aspects of daily life that are often invisible.

While a disorganized room does not mean the owner does not know where things are, it may provide clues to their mood or personality. Excessive accumulation of possessions is common in consumerist societies and can cause space issues. As a result, organizational techniques from other cultures like Japan have grown in popularity in recent years.
