Innovation, by definition, carries the risk of failure. The old cliche about Edison and the light bulb has a point. To tie that into your point, what if Edison had tried hundreds of designs until he found one that worked, but then got the idea for a far better, very different design, and built and shipped that instead? The joke would have a slightly higher number in it. But if he’d given up after the first 50 attempts, who knows when a commercially-successful lightbulb would have come?

Failure isn’t failure until you give up.
