" What is the perfect amount of possessions? I think that most people don’t know. If you have lived in Japan or the United States all your life, you have almost certainly been surrounded by far more than you need. This makes it hard for many people to imagine how much they need to live comfortably. As you reduce your belongings through the process of tidying, you will come to a point where you suddenly know how much is just right for you. You will feel it as clearly as if something has clicked inside your head and said, “Ah! This is just the amount I need to live comfortably. This is all I need to be happy. I don’t need anything more.” The satisfaction that envelops your whole being at that point is palpable. I call this the “just-right click point.” Interestingly, once you have passed this point, you’ll find that the amount you own never increases. And that is precisely why you will never rebound. "
