All of these pieces of advice can be accepted or ignored, in my opinion.
1. Subjective and depends entirely on what the writer wants and / or what the audience wants / expects.
2. I love prologues. Grew up on them. If an agent or publisher refuses my book because of the prologue, I don't want them anyway.
3. Probably sound advice.
5. I've had some people tell me to absolutely not use contractions. I use them now. It makes the writing super formal otherwise. To each their own.
6. Ditto.
7. That actually is good. Head hopping is super annoying and I will not read a book that does it. It just gets too freaking confusing.
8. For many stories, the whole
book is internal monologue from the character. Expressing something in italics, though, can express a single cogent thought. I imagine most people talking to themselves in full sentences from time to time, so that's understandable.
9. Not sure what to think of this one. I'm a bit defensive suddenly because I almost always write in what I believe to be cogent sentences that stand on their own.
10. I was not sure about this one.
I do use this word too much, though, along with "were." I tend to err on the passive side. I write, I guess, in a slightly formal and scientific manner. That's where my passivity sometimes comes through.
12. That would be bad advice.
For the most part I like her blog though.
