We have a biological drive. We eat when we’re hungry, drink when we’re thirsty, have sex to satisfy our carnal urges. We also have a second drive—we respond to rewards and punishments in our environment. But what we’ve forgotten—and what the science shows—is that we also have a third drive. We do things because they’re interesting, because they’re engaging, because they’re the right things to do, because they contribute to the world. The problem is that, especially in our organizations, we stop at that second drive. We think the only reason people do productive things is to snag a carrot or avoid a stick. But that’s just not true. Our third drive—our intrinsic motivation—can be even more powerful.
