I know of those, but I'm absent-minded enough that I often forget there's many better things I could be doing. Seeing my long-range goals and my short-range deadlines in an easy-to-grok format has done wonders for me in the past; I just need a systematic way of delivering that when it's needed. Ideally, the software solution could also pop up when I start viewing a comic book archive, watching a video file, or preparing a snack just because I can't think of anything more pressing to do.
