I'm completely new to book-writing and it felt like a mountain to climb. I have five chapters of around 8 thousand words each to write for the book (I have co-authors, who are also lovely), and the general advice I got was to just take it all one step at a time. This sounds a lot like the way I teach project management and time management to developers, so I used those same skills and created a burndown chart (I blogged about creating these before):
As you can see, there have been some great days, and some quieter days. The flat lines are mostly weekends or days where I was out of the office with other clients. Although I feel slightly overwhelmed (and this doesn't show the edits that come back after I submit each chapter), the graph is at least going in the right direction!
