When storing komono – my term for miscellaneous items – the only way to know the best place for any item is to think yourself into the character of that item. Before I put a komono item away, I joyously climb into the storage space and imagine what it would be like to be stored there. Only then can you know if the Toilet Duck cleaner would be really at home under the bathroom sink.
Once you’re living joyously with all your possessions joyously stored away joyously, you are free to move on to the most advanced joyous level of joyous tidying. See that lump sitting in the armchair watching the football when you want to watch Making a Murderer? Ask yourself this: which gives me more joy? The lump or the empty chair? So ditch him.
