Hi, Charles. I've read this 101-page piece of advice and I found interesting tips, such as the characters and plot's development.
I wrote down some of them that caught my attention:
P.14- What is vigorous English
p.20- I found a contradiction in Your “voice” is your voice. Your “style” is your style.
Does not it contradict all the times that it is suggested that you be concise and use short sentences? What if your style is based on being wordy and using long sentences?
The editing part is a kick in the teeth after reading such an encouraging piece; while the submission guidelines are very precise and useful for somebody who never did it... And it is quite scary too. It made me have butterflies beforehand.
