Thank goodness her bluntness didn't stop me from writing. So here is a glimpse at what I've been told NOT to do in my own work. I hope it helps.
- Make Your Main Character Unlikeable. In one of my earlier novels, my main character was a young, pretty, blond single girl on the verge of inheriting millions. She drove a sports car and lived in a beautiful condo. Can I say that she came across a little conceited? I didn't mean her to be that way. I gave her a nice best friend and the inability to find a love match but it wasn't enough. No one who read that story could connect with her. And if a reader can't empathize with your main character, they aren't going to read your book. So I learned to give my MC something right from the start--a characteristic or problem that a reader might care about her more.
- Dump Endless Backstory into the Opening. Yes, I've did this in several of my books. I felt my reader had to know everything to connect and understand my story. Um, they don't. My job as a writer is to reveal the backstory in sprinkles throughout the book. Learn to slice your words. Find creative ways to add a piece of information. It really does make the story better.
- Describe everything with hundreds of adjectives and adverbs. Describe that tree as tall, green, broad and waving fast in the wing... No, that doesn't work in this day and age. I grew up reading descriptive writing but today the reader wants to get to the plot and not sift through endless words. Everything is faster today. You don't want to bog down the reader with paragraphs of description that does nothing to move the story along.
- Head-Hop. Probably one of the first writing tools I needed to learn about was Point of View. I had to understand that if I wanted to draw the reader into my character, I needed to keep in that character's head and not jump all over the scene into others' heads. It takes work but really makes the story that much better. And yes I had to do a lot of reading on the topic to get it.
- Be so Thin-Skinned you never improve. Ouch. It wasn't easy to read my first critiques from writers and editors. But I had to put aside my feelings and recognize that if I wanted to write and get published, I needed to be open to learn. That meant take advice and recognize my weaknesses. Some writers can't do this and will never improve. That's sad because they are good writers but with a tweak here and there, they can be great writers.
