A few weeks ago I sat down and unsubscribed to almost every list (except for a few). You wouldn't believe the difference in both my bank accont :-) and my productivity. I encourage you, as the end of the year draws near and we prepare for next year, to do the same. I think you will find that this will not only increase your productivity but it will also keep you more focused.
Wishing you and yours a blessed holiday season!
