Freedom: This site offers a shareware download for your Mac or PC called...Freedom. Freedom blocks you from the Internet for any time period you choose, up to eight hours. You can't get back online unless you do a total reboot of your system, and let's face it, that's a pain in the butt when you're in the middle of working and also it feels a bit shameful to go that far just to see if anyone mentioned you on Twitter in the last 20 minutes. It's especially great for writers. Set the deal for a couple of hours and get to work. (This works best if you don't have your iPhone or BlackBerry a few inches away. Maybe you need to put it out in the car, or bury it in a dresser drawer. Not that I know anything about that.)
43 Folders: Time, Attention, and Creative Work: My friend Mike turned me on to this site, which is run by a guy named Merlin Mann. As if having a cool name like Merlin Mann weren't enough, he's also pretty smart about brains and the things we do to avoid using them. Start here. I think my favorite page on the site is First, Care.
This post from Seth Godin's blog. To the point.
The Artist's Way Basic Tools. Okay, a lot of Julia Cameron's classic book on creativity is a little woo-woo for me, but the Basic Tools---morning pages and the artist date---are really great for grounding your inner life when things have gotten a little noisy. And as much as I love and depend on the Internet, there comes a tipping point every day when I've gotten what I need and want from it and the rest is noise.
I'm always looking for more sites about how not to look at sites all day, so if you've got more links in that category, leave them in the comments!
