Deleting and weeding your clutter is extremely hard and needs attention everyday. Weeding your garden (if you have one) is the same idea. Weeding your interior environment of "Extra Stuff" that clutters your space is a daily ritual in editing what you need and what you don't. What is broken or what needs to be put away. Finding places to put your stuff is extremely challenging the smaller the environment.
