Don't you love metaphors? You know you do. They often give a visual to the reader that cannot be expressed in plain language. They connect us to an event in a story that we could not otherwise experience.
Be careful of Dead Metaphors, otherwise known as clichés, in your writing.
Right as rain.
Raining cats and dogs.
Happy as a clam.
At the end of my rope.
Slept like a log.
Just to name a few. My favorite would have to be the Mixed Metaphor. These crazy phrases hit my love of the ridiculous like a ton of bricks. (cliché alert)
1) He stepped up to the plate, and grabbed the bull by the horn.
2) He is a loose cannon that always goes off the deep end.
3) He often shot his mouth off in the dark.
And my all time favorite mixed metaphor:
"If we can hit that bullseye then the rest of the dominoes will fall like a house of cards... Checkmate."
Interstellar spaceship captains can be lovers of the language too.
Watch the metaphors, and have fun creating new ones.
