Build: An Unorthodox Guide to Making Things Worth Making

by Tony Fadell

The best ideas are painkillers, not vitamins. Vitamin pills are good for you, but they’re not essential. You can skip your morning vitamin for a day, a month, a lifetime and never notice the difference. But you’ll notice real quick if you forget a painkiller. Painkillers eliminate something that’s constantly bothering you. A regular irritation you can’t get rid of. And the best pain—so to speak—is one you experience in your own life. Most startups are born from people getting so frustrated with something in their daily experience that they start digging in and trying to find a solution. Not every product idea has to come from your own life, but the “why” always has to be crisp and easy to articulate. You have to be able to easily, clearly, persuasively explain why people will need it. That’s the only way to understand what features it should have, whether the timing is right for it to exist, whether the market for it will be tiny or enormous.
