In my letter to myself, I outline the specific writing tasks I need to do the next day. I might give myself instructions such as, “create a mindmap about XYZ.” Or I might write, “perhaps a metaphor about “xx” would work in here.” With experience, I also discovered that it’s sometimes best to have a spectacularly easy task to begin my writing day, so, from time to time, I would assign myself the job of producing a simple sidebar or a list of bullets. The key thing is, I write these instructions to myself after a time of being thoroughly immersed in the project. Thus, when I come back to it, the letter brings me fully up to speed without wasting any time.
