How To Write A Book
Make sure every sentence is necessary. Make sure every word in every sentence is necessary. If you're not willing to do that, you shouldn't write a book. (Of course, the evaluation of the words and sentences can happen after you write the book.) How does one learn this process? Practice, I guess.
