Over at the Sparrow's Nest Mrs. Wilt has posted about planning your day... Creative Time Management for the Home. Here is an excerpt that I like and have used occasionally (and need to use more often, lol).
"Use a timer. I cannot tell you what a friend my timer is to me. When I have a bit of "working time", I set it for 15 minutes and complete tasks. It works as a mental "coach" to keep me going until it beeps. Although I work fast without it, I go even faster with my timer. It is amazing what one can do in 15 minutes! "
