Goes both ways. When your environment is cluttered, thoughts, worries and concerns about clearing it clutter your brain. A cluttered brain doesn't allow you to fully function in your environment, regardless of its state. Unclutter your mind, so that you can live fully and create the uncluttered environment that you desire. Clutter isn't always stuff, it is anything that is unnecessary and/or blocks you from living and participating fully in this thing called life. Would you like to dump some clutter today?
