So apparently the specific content of whatever I'm supposed to be writing has approximately zero impact on how much procrastination is involved with getting the chapter in question written.
A few weeks ago I was working on the chapter of my book about "Advanced Apache Integration", and since I'm not a huge Apache person I wasn't exactly thrilled about writing about it. As a result I ended up putting it off till the last minute, and wrote most of the chapter (which I'm still not happy with) in the last day or two before the deadline.
Today, I'm working on the chapter about "Best Practices", which is pretty much an excuse to blab on and on about how people should run their projects, and as anyone who's discussed the topic with me knows, I love doing that, so you'd expect that I'd have no trouble kicking out a chapter about it, right?
Wrong.
It's still a few days before the deadline, and I'm still not even close to done...
