How To Write a Non-Fiction Book, version ii, Part 4

Write, write, write. That's the main thing. Through quantity will come quality. Some tips:
On generating words
1. Write fast, edit slow. Set yourself tough deadlines: don't give yourself time to procrastinate. Bash out the words; set up the spell-checker and perhaps basic grammar-checker then write, write, write. I know some books have taken decades to write and some of those have been brilliant. But plenty of great book are written over a few weeks. Go for speed to break that 'getting blocked' pattern.
2. Keep your reader in mind; write for them; not for you. This is critical for non-fiction. Be careful of constantly establishing your credibility (which after all can be done once on the blurb) throughout the text with complicated references, constructions , and jargon. Put across the simplicity which is the far side of complexity.
3. Write even when you don't feel like writing; the process of starting can often change your mood and start the flow. Set a time period and stick to it. And stop when you are still feeling good; then you will wish to re-start tomorrow. If you write to a point of exhaustion you are associating pain with your beloved writing.
4. Look for the fresh angle-what's your thing on time management? Difference, difference, difference is the thing which will pull your book out of the crowd of others. 
On structure
Increasingly readers of business/personal development books prefer them to be shorter and well-structured. One reason I gave my first book Being the Best an A-Z structure was it allowed me twenty-six simple chapters which I know has proved very popular with readers. But too little material means it's not a 'book' and so doesn't sit on shelves. Less is more will be the new trend in non-fiction, especially business books.
On features
Summaries, case-studies and how-to-apply-the-ideas are highly desirable. Too much theory may show how good you are but doesn't help the reader.
