Tam linked this post, and I think it's absolutely brilliant and worth reading.
I waste a lot of time, but I get a lot of things done by not indulging a TV habit. I am, however, trying to make more efficient use of my time, and to take frequent baby steps forward with working on the house. What TJIC says there makes a lot of sense and I've bookmarked it. Maybe you'll find something you can use there, too. :)
