Scrambling to finish writing one book at present, before I embark on another (for the PhD) in a couple of weeks.
My own fault. I could have finished this one a year or more ago. Lost my way. Got bored with it. Now I'm fired up and charging through it (pardon the mixed metaphor) but not taking enough time to look back over old notes and bookmarks.
Need a stern talking to.
Slow down. Breathe. Check your notes before you spend two hours finding out all over again the key dates in the history of the Book of Common Prayer...
