Let's face reality, not very many people enjoy cleaning up their house when it looks like there's too much work that's needed for them to clean it. It's even harder to start when you know that you would have to clean every part of the house. It's even harder to finish once you've started when you become tired after a while. No one wants to spend a lot of time cleaning a big mess and most people don't even have the time to even think about cleaning their own mess.
It's difficult to do, which is why this book is designed for those who either have no motivation to start cleaning their house or have no time to do it. You can probably read this book while you're working on decluttering your house in order to save time. So just start.
