How to Tell a Good Idea From a Merely Exciting One

Every idea feels brilliant at two in the morning. That is not a character flaw, it is how brains work: novelty releases a little hit of reward chemistry, and the hit arrives long before any evidence does. The members on IdeaGrow who ship things consistently are not the ones with the most ideas. They are the ones who have learned to tell the difference between an idea that is good and an idea that is merely exciting, and to do it before the weekend disappears.

Excitement is a feeling. Good is a property.

An exciting idea makes you want to start. A good idea survives contact with a few boring questions. The two overlap less often than you would hope, which is why so many half-built projects sit in our members' folders. Here are the five questions that come up again and again in our forum's "Is this worth building?" threads. Run your idea through them honestly and you will know within an hour whether to keep going.

1. Who has this problem badly enough to change their behaviour?

Not "who might like this", but who is already doing something awkward to solve it: a spreadsheet, a WhatsApp group, a weekly phone call, a paid tool they complain about. If nobody is currently paying for the problem with time, money or annoyance, the problem may not be real yet. Write down three specific people, by name, who fit. If you cannot, that is your answer for now.

2. What does the person do the day after they discover you?

Good ideas have an obvious next step for the user. "Sign up and then..." what, exactly? If the honest answer is "explore", the idea is a feature looking for a product. Describe the first week of use in plain sentences. If the story stalls on day two, the idea is not ready.

3. Why has nobody done this, and why is that about to change?

Either someone has done it (go and look, properly, for twenty minutes) or there is a reason it has not worked. The strongest ideas usually ride a change: a new habit, a new rule, a new tool that made something cheap. Name the change. "People are busier now" is not a change. "Every school in the district switched to the same timetable app in September" is.

4. What is the smallest version a stranger would still pay for?

Strip the idea until it hurts. Remove the app, the dashboard, the automation. What is left that someone would hand you money, or an hour of their time, for? One of our members sold a "coaching platform" idea as a weekly email for six months before writing a line of code. That email was the good idea. The platform was the exciting one.

5. Can you be wrong cheaply?

The best ideas have a test that costs a weekend and a conversation, not a quarter and a loan. If the only way to find out is to build the whole thing, look for a cheaper proxy: a landing page, a pre-order, a manual version you run by hand for five people.

What to do with the answers

• Five clear answers: post the idea in a group and ask for the hardest question anyone can think of. Then start.
• Three or four: the gaps are your to-do list. They are usually cheaper to fill than they look.
• Two or fewer: write it down in your idea journal and let it rest. Ideas that are merely exciting often become good later, when the world changes around them.

The point is not to kill ideas. It is to make sure the excitement is spent on the ones that can carry it. Post your five answers in the forum this week and tag a member whose judgement you trust. The reply is usually worth more than the weekend you would have spent guessing.
