Just saw some pictures of people's tickler files. They are very nice. They are neatly labeled with a label maker. When I made my tickler file, I wrote out days and months on manila folder tabs.
I have neat (and some say artistic) handwriting. I've switched off digital systems to paper a few times, and I think it's because I like the look of handmade notes and doodles. When my next actions start becoming more scribbled than carefully written, it's a barometer for how busy I am and an indicator that I need to slow down and refocus.
I have a label maker, and it is a fun toy. I label many folders at home. But as long as your handwriting is legible, what is the theory behind the label maker?
It seems less efficient to me, as it takes me longer to make a label than to write.
