I have always been a a firm believer that your external spaces are just a reflection of your inner space. The two go hand in hand. If you want to make a change internally, you must first make your external space reflect the changes you long for. De-cluttering and cleanses out things that no longer bring you "JOY" is one of the biggest changes you can make. Marie Kondo has nailed this philosophy in her books! "The Life Changing Magic of Tidying Up" and "Spark Joy". I've applied her methods to all areas of my home, and do clean-outs about every 6 months. If you haven't checked out her books, do yourself a favor and READ THEM!
