Regardless of the size of your home the most critical key to good organization is having ample room to store things. Sometimes that means simply purging the old and streamlining the new. The one year rule should apply - so anything you haven't worn or used in a year goes to charity. You will get a sense of reward and maybe even some good karma. Once you have decided a few things you can live without, and prioritized the things you must absolutely keep - that is when the fun begins! First off ask the question do I want and need to see it? In otherwords does it need to be exposed, or is it better off hidden. Do not simply hide behind a series of doors as that often leads to more clutter. A bit like the glass refrigerator door complex. Yes its a pain to keep your fridge organized, but at the same time it is nice to know where everything is. It is important to find a balance. Glass doors help and can be frosted or even covered with cloth - yet still provide a reflective surface and an idea towards openess.
Again whether it is a Closet, Library, Kitchen, Bathroom or Wine cave - having a place to put everything is key. Buying or even building custom built-in millwork units made by a professional is well worth it. The simple peace of mind that comes from having a place to put things and then knowing where they are can save you hours of stress and avoid a life of misery.
1. Purge what you do not need.
