Gert loves to break the rules, so she enjoyed the piece by Anjali Sachdeva in 'Creative Nonfiction' https://www.creativenonfiction.org/ entitled
5 creative writing rules we could do without
The rules are:
1. Show, don't tell
2. You should only be a writer if you can't bear to be anything else
3. Write what you know
4. Don't use the Passive Voice
5. Use interesting verbs (she's made her own rule here: don't try them in dialogue tags. Stick to 'said.')
It's an amusing and thought-provoking article that would make a great creative-writing class exercise, with students searching out pieces of good writing that violate the rules.
Rule 2 is an interesting one. Gert knows many people who would love to give up the day job and write full-time. It's her view, though, that it's good for writers to have to do something that keeps them in touch with the ordinary world of wage-slaves. Let her state a rule of her own:
if you really are a writer you'll write no matter what.
