Cartoonists don’t think straight.
If you tell them about cars, they think of chewing gum.
If you talk to them about dinner, they think of heel balm.
In short, they force-fit thoughts that may have no connection to each other.
But what’s a cartoonist got to do with the opening paragraphs of your article?
When you think about it, most of us get stuck while writing introductions.
Let’s say we want to write about “growing tomatoes in a small space.”
What are you thinking of right now? Sure, “tomatoes in a small space.” Which is fine to start, but it’s plain and boring.
