I wanted to get the one for grown-ups but the teen one was all they had. Here are the basic points. Figure out the Spaces Where You Keep Stuff (SWYKS -- swicks...sounds cool) and figure out what stuff you are now keeping/want to be keeping in them. Go through each of them, pull everything out, sort it into throw away, give away, and keep piles. Don't keep stuff that you haven't used in over a year, keep your sentimental stashes under control (basically, this is hard for everybody), and be realistic about what you really need and use. And like -- you define your stuff, your stuff doesn't define you. Soooo all of that is great. But I needed more practical tips for the whole house, and I think the grown-up book is probably a little better on those. A good resource to sort out one's feelings on Stuff, but still, practical application will bear out if it is very useful.
