Every writer experiences it sooner or later — that moment when a TV episode ends and you sit back thinking, “Great idea… but I would’ve done it completely differently.” Or you finish a book and your brain whispers, “If only the ending had gone here, not there.” Or a movie introduces a fascinating character who promptly disappears, and you’re left muttering, “They wasted them — I’d have made them the protagonist.”

That instinct — the urge to rewrite, reshape, re-imagine — is not a flaw. It’s the beginning of creativity.

All stories are born from sparks: a scene, a character dynamic, a central what-if. What matters in fiction isn’t where that spark came from, but what you do with it. The goal is not to copy or imitate, but to absorb the essence of what excited you — and then rebuild from the ground up, changing names, settings, motivations, plot structure, emotional stakes and tone until it becomes unmistakably yours.

This guide shows you, step by step, how to transform a pre-existing idea into an original story that stands fully on its own.

1. Identify the Spark, Not the Surface

When you’re inspired by someone else’s work, the danger is grabbing the wrong layer. Many beginner writers cling to surface details — specific scenes, character types, or plot beats — rather than isolating the spark.

The spark is the emotional or conceptual core that excited you.

It might be:

• A lonely detective uncovering a truth that hurts them personally
• A dystopian society where memory is controlled
• A slow-burn relationship between rivals
• A twist that flips the meaning of everything before it
• A moral dilemma that forces a character to choose between love and justice
• A locked-room mystery setup
• A specific mood — bleak, hopeful, surreal

Your first task: strip away every detail except the one thing your imagination refuses to let go of.

Ask yourself:

• What part of the story made me think, “I wish it had gone this way instead”?
• What emotional response am I chasing — tension, heartbreak, triumph, justice?
• What question does the original raise that it never fully answers?
• What possibility did the story ignore that I want to explore?

Once you isolate the spark, the original story’s scaffolding dissolves. You’re left with the seed — now ready to plant into new soil.

2. Shift the Perspective — Radically

One of the fastest ways to turn inspiration into originality is to change who the story belongs to.

For example:

• Instead of the chosen hero, write from the point of view of the overlooked friend.
• Instead of the detective, tell it from the criminal — or a witness, or the victim’s sibling, or the journalist desperate for a story.
• Instead of the magical child, write the exhausted mentor.
• Instead of the action-hero survivor, follow the medic who never wanted to be on the battlefield.

By changing the storyteller, the story becomes unrecognizable.

Write a paragraph answering:

• Who has the most to lose?
• Who has the most to hide?
• Who was ignored in the original story?
• Whose version is more interesting than the protagonist’s?

Once you shift perspective, scenes, motivations, stakes, pacing — everything — becomes yours.

3. Build New Characters, Not Variations

A “similar character with a different haircut” is still a copy.

A new character has:

• Their own goals
• Their own wounds
• Their own voice
• Their own worldview
• Their own fears
• Their own contradictions
• Their own history

Start by defining your main character without referencing the original at all. Ask:

• What do they want?
• What do they need (but don’t know they need)?
• What flaw limits them?
• What is their secret shame?
• Who do they love? Who do they resent? Who do they pretend to be?

Give them a job, culture, family situation, location, hobby, and weakness that’s nothing like the original character.

Suddenly, the emotional engine of the story is different — which means everything is different.

4. Change the Setting — Make It a Character

A shift in location transforms tone, opportunities, culture, conflicts and plot logic.

If the inspiration was set in:

• modern London → move it to a quiet Cornish village
• a sci-fi megacity → relocate to a remote starship, or a failing colony, or a small industrial moon
• medieval fantasy → try a Renaissance-era port, or a desert kingdom, or a frost-bitten frontier
• a suburban home → shift to an isolated lighthouse, a cramped inner-city flat, or a crumbling cathedral repurposed as housing

Ask yourself:

• What can happen in this new setting that couldn’t happen in the original?
• What social or environmental pressure shapes the characters differently?
• What sensory details define the atmosphere?

When the world changes, the story can’t help but follow.

5. Alter the Core Conflict — Retune the Engine

Maybe the original story’s conflict didn’t hit you right.
Good. Change it.

Examples:

• Instead of a hero vs villain conflict, make it hero vs society, or hero vs self, or hero vs fate.
• Replace a physical threat with a psychological one.
• Swap revenge for redemption.
• Replace a power struggle with a moral one.

Ask:

• What conflict excites you the most?
• What conflict would affect your new protagonist the deepest?
• What conflict would not have fit the original story at all?

Once the engine changes, the vehicle can’t be the same.

6. Change the Structure — Break Their Spine, Build Your Own

Take the rough idea and restructure it. Choose a new foundational shape:

• A reverse-chronology mystery
• A “story told in interviews” format
• A dual-timeline past/present reveal
• A countdown structure
• A three-act emotional arc
• A seven-point structure
• A frame narrative (story-within-a-story)
• A novella-style focused arc
• A multi-POV ensemble

Even if the central spark echoes the inspiration, the storytelling architecture will feel new.

7. Rebuild the Plot From the Ground Up

Start fresh.

Forget the original plot.

Write down:

• Your protagonist’s goal
• The obstacle
• The stakes
• The antagonist — personal, societal, environmental
• The midpoint twist
• The crisis
• The climax
• The emotional resolution

Next, sketch ten scenes that logically follow from your unique protagonist in your unique setting facing your unique conflict.

Compare your outline to the original work.

If more than 15% resembles the original structure, twist it again — move scenes, change outcomes, break patterns.

Plot is malleable — bend it until it stops looking familiar.

---

8. Embrace the “What If It Went Different?” Technique

This is a powerful tool.

Take the moment that annoyed you in the original story.

Ask:

• What if the villain wasn’t the villain?
• What if the protagonist failed here?
• What if the couple didn’t reconcile?
• What if the mentor betrayed them?
• What if the real conflict only starts where the original ended?
• What if the death never happened?
• What if the side character was the true focus?

The moment you answer “what if” differently, your story diverges completely.

---

9. Choose a Theme That Matters to YOU

Theme shapes everything — tone, character arcs, ending, symbolism, dialogue.

If the original story was about:

• justice → make yours about mercy
• freedom → make yours about responsibility
• revenge → make yours about healing
• survival → make yours about identity
• power → make yours about sacrifice
• loyalty → make yours about betrayal

Theme determines which emotional notes you hit and which you ignore.
Theme is the soul — and the soul must be your own.

---

10. Change the Ending First — Then Work Backwards

A great trick:

• Write an ending completely different to the source’s.
• Make it darker, lighter, happier, sadder, more ironic, or more heroic.
• Then reverse-engineer the story so it naturally leads to that new final moment.

When the ending transforms, the journey transforms with it.

---

11. Let Your Voice Take Over

Your writing voice — your rhythm, humour, emotional lens, word choice, pacing — is the final layer of originality.

You could give ten writers the same starting spark and each would create something completely different because voice is personal.

Lean into what you do best:

• Dry humour
• Brutal honesty
• Poetic description
• Tight tension
• Warm character-centred storytelling
• Dark psychological depth
• Quick pacing and sharp dialogue

When your voice shapes every sentence, no one will mistake the story as an imitation.

12. Perform a “Similarity Audit” Before You Draft

Before writing:

Make a list with two columns:

• “Original Story Elements”
• “My Version”

Check that:

• Names, places, plot beats, relationships, antagonists, tone, and structure are fundamentally different.
• Your plot does not track the original’s plot in sequence.
• Your characters would not survive in the original world — and vice versa.
• The central conflict belongs to your story alone.
• Your ending is unique.

If something looks too close, change it right then.

---

13. Dive Deep Until the Story Feels Like Yours — Not an Adaptation

The final stage is simple:

Write it.

By the time you:

• change the protagonist
• change the setting
• change the conflict
• change the structure
• change the emotional arc
• change the tone
• change the theme
• change the ending

…your story will share only a faint whisper of DNA with the original spark that birthed it.

And that’s how storytelling has worked since the beginning of time.

Final Thoughts: Rewriting Is Not Copying — It’s Creating

Every genre classic comes from someone taking a familiar idea and twisting it:

• “What if Romeo and Juliet were rival gangs?” → West Side Story
• “What if Sherlock Holmes was Dr Watson’s diary?” → dozens of modern reinterpretations
• “What if Cinderella was a thief?” → countless rewrites
• “What if the ghost was the hero?”

Stories evolve because writers dare to say:
“I can take that spark and build something different.”

And so can you.
