I just watched a great time management lecture from the late Randy Pausch. You can find it at http://video.google.com/videoplay?docid=-5784740380335567758. The slides are at http://www.cs.virginia.edu/~robins/Randy_Time_Management_UVa_2007_slides.html if you want to follow along. The video is about an hour and a half long. It offers some great tips.
