1) First novels have a 90% chance of being complete crap.
It’s okay if you’re part of the 90%.
2) It’s okay to write without a plan and end up with a complete mess on your hands.
Never write without a plan again.
3) Some ideas will fall into the abyss.
Find a new idea.
4) It’s okay if your title is The Headless Fisherman and no headless fisherman appear anywhere in the book.
Titles can be changed. You’re not stuck with them.
5) Sometimes you just don’t know what to do.
Write anyway. This is what revision is for.
6) If your character is getting on your nerves, they will get on other people’s nerves.
Fix them or dump them.
7) It’s okay if your first draft comes up a lot shorter than you intended.
This is why it’s called a first draft. There will be a second draft.
8) Sometimes your characters will fall flat.
Rewrite them or Replace them.
9) If the scene is boring you, it will bore other people.
Liven it up or trash it. You don’t need it.
10) Sometimes your story will have too much going on.
Get to hacking.
11) It’s okay if an agent doesn’t want your story.
Try other options or move on.
12) If you’re halfway through and realize you hate it or like it but wouldn’t read it, it’s okay to set it aside and work on something else.
Don’t force it. There’s no point.
13) You’re going to doubt yourself. You’re going to worry. You’re going to be afraid. Keep writing.
