Does anyone remember such a book being mentioned?

Thanks in advance.

There's also this book I checked out from the library a couple of months ago: It’s Hard to Make a Difference When You Can’t Find Your Keys by Marilyn Paul.

It's not as easy a read but it went into more psychological reasoning as to why people keep clutter.

Here are some of my notes from it (her example questions/answers, not mine):
~~~~~~~~~~~~~~
"There is an exercise that I do in my workshops that I call ‘choosing a new habit.’ In it, you write down how you do things now, including your current habit, your current thinking, your current belief, and your current result. And you write down your desired result, the new habit that will get you the new result, and what you would need to be thinking and believing, in order to get a different result. Then you make a choice: Which do you really want? I encourage you to try this yourself, using the example that follows as a model.

1. Choose one habit that you want to change and describe your current behavior in simple terms. When I eat a bag of popcorn and drink a bottle of water, I leave the empty containers in the car.
2. Write down the thoughts that accompany this habit. I’ll come back later and get them.
3. Identify the belief that underlies this behavior. It could be any thoughts you might have that support your current habit and sound true to you. Details are unimportant.
4. What is the result that you get from this habit? Messy car.
5. Now describe your desired result and the difference it will make to you. A clean interior and much more pleasant transportation.
6. What new habit will help you get that result? I bring in everything from the car at the end of the day.
7. What would you have to be thinking in order to carry out this new habit? I enjoy a clean car and it’s easy enough to bring in everything right then.
8. What belief (or beliefs) would support this new habit? (This new belief might be the opposite of the old belief, but not always.) Small details make a big difference. I am worthy of dignity.

When you compare steps 1-4 with steps 5-8, you can see that you can make a choice. At this point, you will see that you will need to make this new choice over and over again until it is no longer a choice – it has become a new habit."

After copying/pasting that, I think I need to do that thinking exercise with some areas of my life - it sounds really good, actually.

One small book I've often mentioned here and it simply states the benefits of eliminating clutter, it's "Clear your clutter with Feng Shui" the feng shui is very basic and not accentuated, they emphasize the logic of eliminating clutter and what it can do to enhance your well being. I pick it up and read different chapters from time to time.
