"Even Lazy People Can Do It! First-Time Decluttering" Just do it, and throw things away. If you're unsure where to start, start with one thing in front of you. If "sort of," "but," or "it's a shame" come out of your mouth, throw it away without hesitation. Just the rule of not putting things on the floor will make things cleaner and cleaner!
