Haha, I never had the patience to analyze it as you did. In my case my lifestyle did it for me. The first step, I had to live in a student home in a developing country (Romania) and my space allowance was the tiniest wardrobe ever. I guess I never passed that moment, even after I bought a house and a car and all the comfort. I just feel more comfortable if I know exactly the amount of the things I have have in life. I read this in a book so many years and I loved the concept, to be able to count them all. Arizona seems like a nice place, if by any chance I will pass bye I will invite you to see my bag and have a beer :D
