It’s like childbirth. (Apologies if this metaphor doesn’t work for you.) Scary, exhilarating and, yes, painful. To be precise, it feels like the last stage of giving birth. Suddenly it’s going faster, there’s an unstoppable momentum and you know there will be a result that will make it all worthwhile.

And yes, I’ve been through it three times (childbirth, not writing a book) with two remarkable daughters (see Amanda running the Boston Marathon here) and a remarkable son to show for it.

I’ve still got a lot to write and wrestle with… onward.
