I saw this site on DIGG once, but now I read it every day. I read about a dozen blogs every day, but this is one of two sites (Seth Godin's is the other) where I constantly link to the posts. He's really helped me get more organized, and more centered. I've found that I get more done every day by doing less. One piece of advice I tell people all the time is to sort your to-do list into groups and call them projects. And then focus only on three projects. It's easier than doing them catch-as-catch-can, and it gives you a sense of accomplishment when you're done. I use that at work, around the house, and in my personal relationships. Nothing else you find in the way of advice is going to make you both more productive, and more spiritual.
