Many years ago I noticed that using a paper almanac was very helpful in certain situations, actually helping me make more use of the Google Calendar. Two years ago I started using a bunch of notebooks (basically one notebook per topic) because writing ideas down is very helpful to me. Just at the end of the year I got a sketchbook for drawings. At the beginning of the year I got a bunch of Post-Its and started my very own conspiracy wall (the conspiracy is that there's stuff I'm supposed to do at some point).
