Most chapters are somewhere between 2000 and 4000 words, but if you want to write a short chapter of 1500 words, that's fine too. Remember that you can't do any of this wrong, and it's your choice.

Here's a method that I use when I'm writing a chapter in a book. Adapt it to your own needs.

1. Reread your notes

Reread the notes that you've made during this week.

2. Talk to yourself on paper

Then take five minutes and write out exactly what you want to include in this chapter. This isn't an outline; your notes can be as brief, or as lengthy as you wish. I usually talk to myself on paper, like this:

"What do I want to cover in this chapter? I want the reader to understand (this process/ theory/ idea/ method). I also want to include these five anecdotes. What do the anecdotes show? The first one shows that…"

By talking to myself like this, I eliminate performance anxiety. Some writers do the same thing by writing their chapters as letters: they can take it easy, as if they're talking to a friend. The big benefit of using a method like this is that it does away with formality and stiffness.

3. When you're ready, write

When you feel ready, start to write. As you're writing, just get the words out as quickly as you can. It's useful to set a goal for the number of pages in an hour. I usually aim for three pages an hour. However, if you feel that having a number of pages that you "must" write an hour stresses you, then don't set a goal like this.

When you're writing:

• Turn on the answering machine, and turn off your email program;

• Close your office door;

• Set yourself goal of either pages written, or words written;

• Don't reread your notes. If you need to look something up, just write "tk" which is an old printer's mark meaning "to come,” and keep on writing. If you stop to look something up it may derail your train of thought. Plus you may think: oh, I need to cover this, and this, and this must go in. Assure yourself that you won't be able to cover everything. Trust that your subconscious will deliver the material which needs to go into the first chapter ;

• Keep going even if you're sure that what you're writing is less than your best work. You can tidy it all up later. Just get the words down.

If you find that your writing goes slowly with this first chapter, that's normal. First chapters are always slow to write, because you haven't found the right tone and voice in which to write your book. Once you find those, the writing will go much more easily. Because first chapters are always slow, it's important that you don't leave your desk until you've written the number of words you set out to write.
