I'm removing myself from countless email lists that I amcurrently subscribed to. It is quite lovely. I hit the unsubscribe and my three days later my mailbox is half the size. I'm even doing this at work, Sun Microsystems be damned, I need not to get three emails a day about new products. If I need something, I'll check it out myself.
I just cancelled netflix for the third time. I love it, but honestly, when do I have time to sit and watch a movie other than on a plane? If I'm lucky, I'll get it from the library. If I find myself missing it, I'll start up again.
As for culling, everytime the different charity organizations call, I'm happy to donate.
Ditto for books, if I don't get it at the library, I buy it used. If I don't feel its worthy of keeping, I either donate to the Seattle Public Library or package them off to send to the book exchanges at the various Admiral's Clubs throughout the system.
I'm using freecycle right now to rid myself of a few things that you couldn't even believe that people would want -- tires, diving weights, cleaning supplies. Its amazing what you can share with others who may find treasure in your cast offs.
Check it out yourself. Freecycle.
