That Idea Won't Leave You Alone — Here's How to Tell If It's Worth Chasing

I once spent eleven months on a project I knew was wrong by month three.

Not wrong in a productive, difficult, this-is-hard-because-it-matters kind of way. Wrong in a quieter, more deflating way — the kind where you sit down to work on it and feel nothing. Where finishing it starts to feel less like an achievement and more like an escape from a hostage situation you walked into voluntarily.

I finished it anyway, mostly out of stubbornness. But those extra eight months taught me something I genuinely wish I'd known earlier: knowing when to commit to an idea is just as important as knowing how to execute it.

The Problem with Creative Excitement

Here's the trap: creative excitement and creative potential feel identical in the first few days. Both give you that buzzy, caffeinated energy. Both make you want to drop everything else and start sketching, outlining, building. Both feel like the beginning of something real.

The difference only reveals itself over time — and by then, you've often already told people about it, rearranged your schedule around it, and mentally committed to it in a way that makes pivoting feel like failure.

So the question isn't really is this idea exciting? It's what kind of exciting is this?

And to answer that, you need a few different lenses.

Lens One: The Resistance Test

This one sounds counterintuitive, but stay with me. The ideas worth pursuing long-term are almost never the ones that feel effortless at the start. They're the ones that feel effortless and slightly terrifying.

If an idea makes you a little nervous — if there's a voice in your head saying who do you think you are to make this or what if you're not good enough to do this justice — that's actually a signal worth paying attention to. Resistance, the kind Steven Pressfield wrote about, tends to cluster around the work that matters most to you. Small, easy ideas don't generate much resistance. Big, meaningful ones do.

Ask yourself: does this idea scare me a little? If the answer is no, it might be a fun quick project. If the answer is yes, you might be onto something worth a longer commitment.

Lens Two: The Obsession Check

This is the one I use most often now. Before I commit serious time to anything, I give myself a few weeks to just think about the idea without actively working on it. I let it sit. I go about my regular life and I notice whether the idea keeps showing up uninvited.

Does it interrupt you in the shower? Does it make you want to take notes at inconvenient moments? Do you find yourself mentally casting it, or imagining specific scenes, or solving structural problems while you're trying to fall asleep?

That kind of persistent, intrusive thinking is a really good sign. It means your subconscious has already decided this is interesting and is doing background processing without being asked. That's free creative labor — and it only happens with ideas that have genuine staying power.

Conversely, if you have to remind yourself to think about an idea, that's useful information too.

Lens Three: The Expansion Test

Here's a practical one. Sit down with the idea and spend twenty minutes just asking questions about it. Not planning it — questioning it. What happens right before this story starts? What happens ten years after it ends? What does the world look like from the perspective of the least important character? What's the version of this that's completely different but somehow still the same idea?

Does the idea get bigger the more you poke at it? Or does it start to feel thin?

Ideas with real depth tend to expand under pressure. You pull one thread and find three more. You answer one question and it opens five others. That generativity is a strong indicator that there's enough material here to sustain a long project.

Ideas that are mostly a vibe or an aesthetic tend to deflate under the same pressure. They were always more about a feeling than a foundation. Those can be beautiful short pieces — a single illustration, a flash fiction, a mood board. But they usually can't carry a novel or a series or a year-long project.

Lens Four: The Honest Stakes Question

This one requires you to be a little brutal with yourself.

Why do you want to make this? Not the nice answer — the real one.

Is it because the story genuinely matters to you, or because you think it'll get attention? Is it because you're obsessed with the subject matter, or because someone you admire made something similar and you want that feeling too? Is it because you have something specific to say, or because you feel like you should be working on something big right now?

None of those second options are shameful motivations. But they tend to run out of fuel around month four, right when the project gets hard. Extrinsic motivation — attention, validation, keeping up — is a terrible long-term energy source for creative work. Intrinsic motivation, the kind rooted in genuine curiosity or personal necessity, is the only thing that actually gets you to the finish line on a big project.

When Quick Experiments Are the Right Call

Not every idea needs to be a commitment, and knowing when not to go deep is just as valuable as knowing when to dive in.

Some ideas are perfect as quick experiments — a short story, a sketch series, a one-off piece that lets you play with a concept without signing your life over to it. These aren't lesser projects. They're a different kind of project. The goal is to make something complete and satisfying within a contained scope, not to hold back on a big idea.

If an idea doesn't pass the expansion test, or if the obsession check reveals it was really just a passing fancy, give it a tight deadline and a small format. Make it fast, make it fun, and let it be what it is.

The Decision You'll Actually Respect Later

Here's what I wish someone had told me before that eleven-month slog: saying no to the wrong project at the right time isn't giving up. It's editing. And editing is one of the most important skills a creator can develop — not just on the page, but in the decisions you make about where your time and energy go.

The right idea for a long commitment will survive a few weeks of honest scrutiny. It'll still be there, still nagging at you, still expanding every time you poke it. That persistence is the clearest signal you've got.

Trust it.
