Regarding "100 things" -- if you dig into it a little, most minimalists stretch their definitions and counting abilities quite a bit -- they exclude household items, they group "underwear" into a single item, etc.
I'm not interested in getting down to any arbitrary round number amount of things, but I am already quite spartan and am interested in getting rid of stuff that is lying around that I don't use, don't want, don't need.
In general, most "stuff" to me weighs me down. Every item of stuff comes with the following additional tasks: acquiring the money to acquire it, acquiring it, locating a place for it, maintaining it (washing/dusting/vacuuming), sometimes buying other stuff to go with it (a grill begets grilling tools, grill cleaner, a grill cover, a grilling apron ...), and often eventually getting rid of it. All of that takes time and mental energy that I'd rather spend elsewhere.
Just like I want to be free from my job and my debt, I'd like to be free from most of my stuff.
I like the "try before you buy" approach that several have mentioned. I plan to do that. I've already done that to a certain degree and have enjoyed it immensely each time.
As for the "we love our stuff" people...I say live and let live. I'm not going to try to convert anyone else to minimalism, and I assume those who prefer more stuff and posted on this thread wouldn't mind me being spartan. I was mainly interested if there was anyone else here who had tried it and hadn't liked it.
As far as my kids go, I'm probably going to hold off on the minimalism until they're out of the house. Just because I want to live in a teardrop trailer doesn't mean imposing that on them is the right thing to do. Plus, the great State of Idaho probably wouldn't agree with me that it was in the best interest of the children, especially since it would be a very unconventional lifestyle.
