Another great spotlight!
I think I need to read your book because it seems I am forever writing! Whether it’s replying to emails, writing up guides/instructions, announcements, forum posts, legal correspondence, the list goes on - it’s actually quite therapeutic when I get a chance to actually do a bit of coding 
Interesting that I have got into the habit of doing some of what you recommended. I will usually start a document by writing up some brief notes of what I want to include, sometimes elaborating if I think it’s a complex point or one I might forget. I also find that sometimes I am working on a paragraph and if after multiple edits it still doesn’t feel quite right - I’ll move the one I worked on down, and start writing a new version from scratch, working on both until one of them feels right. I also start work on some documents weeks before I probably need to, because I’ll not want to miss anything important. Probably not ideal and why I should read your book
