If you have to do or like to do record-keeping, I'm sure you'll find these free organizers and calendars to be very handy. Even if you're not a teacher, you may find some of the charts and templates useful for studying, for planning a project, and for journaling.
Donna Young's site has a well-organized range of materials for almost every purpose imaginable. Time Savers for Teachers also offers some free downloadable record templates for teachers. I recommend a visit to both sites to see which materials might serve your purposes and also to get ideas of how to use them.
