Start with What You Actually Notice

Go for a walk without a notebook open, but with your attention turned outwards. The aim is not to find a metaphor. The aim is to find a detail. A metaphor built from a real observation carries weight because it has been seen, not invented. So look for the specific, the slightly odd, the thing you would normally walk past. The way a puddle holds a perfect grey square of sky. The chipped edge of a kerb where a dandelion has pushed through. The bus shelter glass scratched into a fog by someone’s keys. These are not poetic in themselves. That is the point.

As you walk, resist the urge to name a feeling. If you catch yourself thinking, “That looks lonely,” pull back. You have skipped a step. The observation is the raw material. The feeling will come later, and it will be truer if you let the detail lead.

Write the Detail Down Before You Interpret It

When you get home, write down five things you noticed. Use plain language. No adjectives unless they are precise. “A black bin bag split open, revealing orange peel and a single shoe” is better than “a sad bin bag.” The first gives you something to work with. The second has already done the emotional work for you, and it will feel forced when you try to build a metaphor from it.

Keep a notebook or a note on your phone for this. The discipline is simple: collect, do not conclude. Over a week you will have a small archive of ordinary observations. Some will be duds. That is fine. A metaphor is a lucky collision between a detail and a feeling, and you need a decent pile of details before the collision can happen.

Find the Feeling That Matches the Detail

Now look at your list. Which detail keeps pulling at you? Not the most dramatic one, but the one that has a strange hold. That is your candidate. Next, ask what abstract feeling or idea it might connect to. Do not force a grand theme. Small, specific emotions work best: the tiredness of a long week, the relief of a cancelled plan, the quiet after an argument, the nervous hope before a first date.

Let the detail suggest the feeling. If the detail is a puddle holding a square of sky, the feeling might be a momentary calm. If the detail is a weed pushing through a kerb, the feeling might be stubborn persistence. Write down the pairing in a plain sentence: “The puddle holding the sky is like a moment of calm in a noisy day.” That is not yet a metaphor, but it is the spine of one.

• Vehicle: the thing you noticed (the puddle).
• Tenor: the feeling or idea (the calm).
• Ground: what they share (containing something vast in a small, temporary space).

If you cannot name the ground, the comparison is probably forced. Put it aside and try another detail.

Test the Metaphor by Reversing It

A quick test for forcing: reverse the comparison. Does it still make sense? “A moment of calm is a puddle holding the sky” works because calm can feel like a small, reflective pause. But “a cancelled plan is a chipped kerb” might not work unless you can explain why. The reversal test stops you from bolting two things together just because they sound nice.

Another test is to ask what the detail does not share with the feeling. A good metaphor admits its limits. If you say a friendship is a bus shelter, you need to know how it is not one. That awareness keeps the comparison honest and stops it from becoming a cliché. Write a sentence that begins, “It is not that…” and finish it. This often sharpens the metaphor rather than weakening it.

Refine the Metaphor on the Page

Now draft the metaphor into a sentence or two. Start simple. “The week had been a split bin bag, its contents spilling onto the pavement.” Then revise. Cut any word that explains the comparison. Trust your reader. If you have chosen the right detail and the right feeling, the connection will land without a nudge.

Read it aloud. Does it sound like something you would say, or something you think a writer should say? If it is the latter, simplify. British English often rewards understatement. “The week had been a split bin bag” is stronger than “The week had been an utterly devastated bin bag of despair.”

Finally, let the metaphor do one job. Do not stack three comparisons on top of each other. One good metaphor, built from a real observation, will carry more weight than a paragraph of decorative ones. Then go for another walk. The next detail is already waiting.
