Even before I started typing what I had hand written, I was already mentally editing it. And tonight as typed three more chapters, I found them too long and somewhat repetitive so I cut out a great chunk on two of them and condensed some of it down. My notes for Chapter 11 were especially long, a lot had to be taken out. I carefully decided what needed to go and what seemed repetitive from previous and subsequent chapters (those I have yet to type) and within each chapter itself.
This definitely is how to write, I have been told.
As of now, typing chapters 12-15 and the epilogue remain to be done. One of these is already pretty short. I'm anxious to see how many I get typed tomorrow.
