Your main character wants something badly enough to act. That is a strong start, but a story does not move because a hero has a wish. It moves because of what's standing in your hero's way? The answer creates tension, gives scenes a reason to exist, and turns an idea into a story readers want to follow to the final page.
For a new writer, the obstacle can feel like the difficult part. You may know your heroine wants to save the family business, solve a disappearance, leave a damaging relationship, or finally tell the truth. Yet every next chapter feels flat. Often, the missing ingredient is not more description or a bigger cast. It is a meaningful force that makes the goal hard to reach.
What's standing in your hero's way?
The short answer is: something that matters. A late train is an inconvenience. A late train that stops your hero reaching their child before a custody hearing is an obstacle. The event is similar, but the personal cost is completely different.
A useful story obstacle does three jobs. It blocks progress towards the goal, forces the hero to make a choice, and reveals something about who they are. If it only delays the action, it may be a detour rather than real conflict.
Think about your hero's goal in plain language. They might want to earn a promotion, find their missing sister, publish a book, protect a friend, or be accepted by a community. Then ask what would make success genuinely difficult, not merely inconvenient. The best answer is rarely a single problem that can be removed in one scene. It is a pressure that keeps changing shape as the story develops.
External obstacles create visible action
External obstacles are forces outside the hero: a rival, a deadline, a law, a storm, a lack of money, a secret, a dangerous setting, or a family expectation. They give readers something they can see happening on the page.
A mystery writer may give their detective a witness who refuses to speak. A fantasy writer may place a guarded border between the protagonist and the person they need to find. In a contemporary novel, a mother might need a new job while caring for a child and hiding a painful truth from her partner.
External conflict is especially useful because it creates immediate scene questions: Will she get the witness to talk? Can he cross the border? What will happen when the truth comes out? But visible trouble alone is not enough to carry a novel.
Internal obstacles make the conflict personal
Your hero may also be standing in their own way. Fear of failure, pride, guilt, grief, perfectionism, mistrust, or a need for control can cause them to choose badly even when a clear solution is available.
This does not mean your character should behave irrationally just to extend the plot. Their inner struggle needs a reason. Perhaps your hero refuses help because they were betrayed before. Perhaps they cannot forgive because forgiveness feels like excusing harm. Perhaps they keep revising their manuscript instead of submitting it because rejection would challenge the identity they have built around being talented.
The most compelling obstacles often combine the outer and inner story. A journalist may need to expose a powerful figure, but fear losing the family who taught her to stay quiet. A young magician may need to trust a team to defeat a threat, but has survived by relying only on himself. The plot problem and emotional problem push against each other.
Other people should want something too
A villain is not required, but opposition is. The person blocking your hero may be decent, frightened, mistaken, or pursuing a goal that clashes with your hero's goal. This is often more interesting than making them cruel for the sake of it.
If your protagonist wants to sell an inherited house, their brother may want to keep it because it is the last connection to their parents. Both characters have something to lose. The conflict now has emotional weight, and neither person needs to be a caricature.
Give the opposing character a clear motive, a plan, and enough power to affect the outcome. If they can be defeated by one quick conversation, they are unlikely to sustain a full story.
Build obstacles one scene at a time
A large story problem becomes believable through smaller blocks. In each scene, your hero should pursue something specific, meet resistance, and leave in a changed position. They may gain a clue but lose an ally. They may get the meeting they wanted but say the one thing that damages their chance of success.
This pattern stops scenes becoming exchanges of information. Instead of writing a scene where your character simply learns that the old manor is for sale, let them try to persuade the owner not to sell it. The owner agrees to listen, then reveals they have already accepted a higher offer. Your hero has new information, but they also have a harder problem.
Do not make every setback louder than the last. Variety matters. One obstacle may be practical, such as a missed deadline. The next may be relational, such as a friend refusing to help. Another may be moral: the only available solution could hurt an innocent person. Different forms of pressure keep the story from feeling repetitive.
A simple planning prompt can help: at the end of every scene, write, “Because of this, my hero must now…” If you cannot finish the sentence, the scene may not have changed the story enough.
Raise the cost, not just the noise
Many early drafts add danger whenever the middle starts to sag. More arguments, more villains, more disasters. Sometimes that works, especially in thrillers and adventure stories. Yet bigger events do not automatically mean bigger stakes.
Stakes rise when the consequences become more personal, more permanent, or more difficult to accept. Missing an interview may become losing financial security. Losing financial security may force your hero to return to a place they escaped. Returning may bring them face to face with the person whose approval they have spent years chasing.
Ask what success will cost as well. A hero who gets everything without sacrifice can feel less believable than one who must choose between two meaningful losses. Your character may solve the crime but expose a loved one. They may achieve their dream job but realise it demands a life they no longer want. The right trade-off depends on the kind of story you are telling, but it should reflect your theme and your hero's values.
Test whether your obstacle is strong enough
When you feel stuck, do not immediately add another twist. First, examine the obstacle already on the page. A strong obstacle usually passes these four checks:
- It directly interferes with the hero's current goal.
- It cannot be solved without effort, risk, or a difficult choice.
- It exposes a weakness, belief, or value in the hero.
- It changes the situation when the hero responds to it.
Be fair to your characters, too. Coincidences can begin a story, but they should not repeatedly rescue your hero from consequences. Readers invest when solutions grow from a character's decisions, skills, relationships, and hard-won change.
When the hero keeps choosing the easy route
Sometimes the real issue is not the obstacle. It is that the writer is protecting the protagonist. You may avoid letting your favourite character fail, look foolish, disappoint someone, or make a morally messy decision. But struggle is not punishment. It is the place where readers learn what your hero is made of.
Let them try a sensible plan and discover its limit. Let them misunderstand a person they love. Let a win create a fresh complication. Then allow them to learn, adapt, and act with greater honesty. Growth feels earned when it costs something.
For memoir and life writing, the same principle applies with care. The obstacle may be shame, silence, family loyalty, illness, or the gap between what happened and what you were able to understand at the time. You do not need to invent drama. Look closely at the forces that made the moment difficult, and write with compassion for the person you were.
Your hero does not need an impossible mountain in every chapter. They need a goal worth pursuing, a barrier that matters, and a reason to keep going when walking away would be easier. Start there today: give your character one honest problem they cannot ignore, then let their next choice reveal the story only they can tell.
