Science, my lad, is made up of mistakes, but they are mistakes which it is useful to make, because they lead little by little to the truth.

Mistakes Are How You Learn Forward

We tend to think of science as this pristine march toward facts, but the real story is messier and more human. Every major discovery came wrapped in wrong turns—bad data, dead-end experiments, theories that looked brilliant until they weren't. The insight here is that these weren't failures in the traditional sense. They were actually the work itself, the only way forward available at the time.

This matters because most of us live under the weight of perfectionism. We avoid starting things because we might do them wrong. We quit after a setback because it feels like proof we're headed nowhere. But Verne is pointing at something liberating: mistakes aren't the opposite of progress. They're often the machinery of it. A failed attempt teaches you something concrete. A wrong answer narrows the field. You move incrementally, learning what doesn't work until you stumble toward what does.

The non-obvious part? This applies way beyond labs. Learning a skill, building a business, even changing a habit—they all work the same way. The people who get good aren't the ones who avoid mistakes. They're the ones who make useful ones, stay curious about why things didn't work, and keep adjusting.
