Swedish word lagom means just the right amount, and it is deeply rooted in the Swedish culture, says a decluttering expert cited here in this report on how to clean up. Anything that you haven't used for a long time, set it aside, give it away, keep only the important things. Its called death cleaning here but it is more than that, just keep life simple, don't accumulate, and it makes it easier to enjoy life. All the clutter only comes in the way, more of a hindrance to living.
