If you are like most people, you have too much clutter in your life. As Walsh defines it, clutter is anything in your living space that doesn't add value to your life (and if you think about it deeply, that's probably most of your stuff). Reading this spurred me into a frenzy of decluttering, in which I discarded stacks of old magazines that I'll probably never go back to, a bunch of small kitchen appliances that we never use, and more. I filled several giant "contractor-size" garbage bags from my office/music-room alone.

It's hard to keep on top of the clutter, but Walsh's book certainly puts you in the right mindset.
