Shiny Object Syndrome: A Filter for New Ideas

Every new idea costs you the one you’re working on. Some trades are worth it — that’s the part nobody says on either side of this argument. The anti-shiny-object crowd acts like focus is a religion and curiosity is sin. The idea-surfing crowd acts like switching is a personality trait. Both are wrong, and the fix is a filter, not a vow of silence.

I’ve spent years being the guy who chases the new thing, and I wrote honestly about it in my post on shiny object syndrome and why the grass isn’t always greener. This post is the tool that came out of that self-audit: the 90-day rule, the idea parking lot, and the three questions that decide whether a new idea earns your attention or just your daydreams.

Why New Ideas Feel So Productive

Sit with the actual mechanics for a second, because shiny object syndrome isn’t a discipline failure — it’s a prediction error with a chemical tail. A new idea gives you the full fantasy version: the imagined outcome, uncompressed, minus all the boring middle. Your current project gives you the real version: half-finished, with today’s obstacles attached. Of course the new idea looks better. You’re comparing a movie trailer to your own work-in-progress footage.

Worse, starting something new produces the feeling of progress without the substance. New notebook, new domain name, new plan — dopamine all the way down, and nothing shipped. I’ve called this out before as the trap inside the alternative to hustle culture: motion masquerading as momentum. The tell is simple. Progress compounds and feels heavy. Novelty spikes and feels light. If your week felt great and your project didn’t move, you bought the spike.

The 90-Day Rule

Here’s the core rule: no switching before 90 days of honest effort on the current thing. Not 90 days of thinking about it — 90 days of logged, real attempts. The logic is arithmetic, not motivational:

• Most ideas fail at week 3-6, when the novelty curve crosses the effort curve. Switching at week four doesn’t test the idea; it tests your tolerance for the dip — which you then get to test again on the next idea, forever.
• Ninety days is the minimum for honest feedback. Most projects show their real shape — actual growth rate, actual enjoyment, actual economics — only after a full season of effort. Earlier data is mostly your mood.
• The rule removes the decision from the moment of maximum temptation. Deciding in advance whether you’re allowed to quit is like automating a transfer: you’re making the choice when calm and obeying it when tempted.

One honest carve-out: the rule applies to the main project, not to experiments. A side experiment that costs two hours a week is fine — the rule exists to stop serial abandonment, not to make you a martyr. The line is whether the new idea is replacing the core thing or coexisting with it. Replacements need 90 days of evidence. Experiments just need a boundary.

The Idea Parking Lot

The parking lot is the single tool that made focus sustainable for me, because it gives novelty a legal home. It’s a note with five fields per idea — nothing more:

• The idea — one sentence, no pitch deck.
• Why now — what specifically triggered the excitement? (A video? A bad week? A real observation?)
• What it replaces or extends — does it compound with the current thing or compete with it?
• Earliest evaluation date — usually 90 days out. No peeking before then.
• One sentence on the boring version — what would the first month of actual work look like?

Writing the idea down does something counterintuitive: it satisfies the capture urge without the switching cost. The idea doesn’t die; it waits. When the evaluation date arrives, most of them look different — the urgency evaporated, which tells you it was mood, not signal. The ones that still look good in 90 days get promoted to a real experiment with real boundaries. That’s how you stay curious without staying scattered. This is the same design principle behind every good system I’ve written about here: decisions made once, in advance, by a calm brain — the same reason I automate money and pre-commit to buying delays.

The Three-Question Filter

When an idea survives the parking lot, run it through three questions before it earns hours:

1. Does it compound with what I already have? An idea that stacks on your existing skills, audience, or assets is worth 10x one that starts from zero. The blog I’ve written for years compounds every time I add to it — that’s the entire argument in my post about content as leverage from zero. A pivot to something unrelated doesn’t compound; it liquidates.
2. Is it a solution or an escape? Be honest about the trigger. If the excitement started the same week your current project got hard, that’s not opportunity knocking — that’s an exit disguised as a door. New ideas chosen in a dip are chosen by the dip.
3. What does it actually cost? Not money — hours, focus, and the compounding you’d interrupt in the current thing. Write the number down. Ideas priced at “free” are always hiding the biggest bill, which is the months they steal from the thing that was about to work.

If the idea answers all three well — compounds, isn’t an escape, and the cost is one you’d pay on paper — it’s a legitimate pivot, not a shiny object. Real pivots exist. They just look like decisions, not seizures.

When Switching Actually Is Right

Straight talk, because the 90-day rule can turn into sunk-cost worship. Switch when the evidence, not the mood, says so:

• The feedback is real and repeated. Not one bad month — a pattern across your honest log: no traction, no economics, no enjoyment, quarter after quarter. If the 90-day runs keep confirming the same negative signal, the filter worked; it told you to move.
• The ceiling is visible and low. If you can see the maximum outcome and it doesn’t justify another year, that’s not quitting — that’s reading.
• The new idea passes the three questions AND the old one fails them. Pivots should be affirmative decisions, not reflexes. Both sides of the trade get examined; that’s what makes it a trade instead of a bounce.

What this all protects is the thing focus actually requires: enough consecutive hours on one thing for compounding to start. I’ve argued before in my post about the power of focusing on one thing that depth beats breadth at almost every life stage where results matter — the filter above is just that argument with a protocol attached.

Your One Step

Create the parking lot today. One note, five fields, and put every current itch in it with an evaluation date 90 days out. Then go back to the main thing for the rest of the afternoon, guilt-free — the itch is on the calendar now, which means it owns a time slot instead of your attention. If, at day 90, an idea still passes the three questions, give it a real trial with real boundaries. Until then, your job is wonderfully boring: keep showing up to the thing that was about to work.
