In high school, I tried a month of using a Day Timer planner. It was nice and I liked the small wirebound planners, but I ended up using a Day Runner planner even though the pages tended to rip out because it only used a three ring binder. In college I went to a Franklin seminar and started using the Franklin system. While the actual pieces of paper weren’t too different from what I had used before, the training that went along with it was very valuable.
I stuck with the Franklin for about six years, but eventually found that I was at my computer enough I could rely on a digital calendar. My switch to digital was complete when I finally moved to a Blackberry that could sync over the air with my calendar, contacts and email. The only think I’m really lacking at this point is a robust synchronization for Omnifocus tasks with my Blackberry.
