A deadline met!

Around a year ago I was invited to join a group of people writing a book, to which each of us is contributing one chapter. I was (and am) enthusiastic because the contributors (most of whom I know, at least professionally) are encouraged to "write in a lively style, deliver lots of interesting content, introduce and analyze intriguing trends and problems, take a chance and prognosticate". Cool! Permission to be opinionated! The deadline for submission of the first drafts is the end of February. My goal was to have mine done by the first week in February. Today I sent it off to the book's editor. No doubt I'll need to do extensive revisions after receiving the editor's comments, but for now I'm heaving a sigh of relief. It's been fun, and I love writing books, but I find the process very time-consuming and mentally tiring.
