This month, I'm pretty obsessed with Time Ladders. I suppose the first one I saw was this one, created by Benjamin Franklin as he planned how he would spend his day.
You can find it here, in the free online version of his Autobiography, provided by Gutenberg.org (see pp. 68-69):
However, there are different ways to build a Time Ladder, and different uses for it. I'm discovering that they really help me in planning out how much time a project should take, from research to final draft, among other things.
For more examples, check out "time ladders" as a search in Pinterest or Instagram.
