Curiosity is the engine of achievement.

The line frames curiosity not as a pleasant trait but as a driving mechanism: the force that initiates learning, experimentation, and sustained effort. “Engine” suggests energy, direction, and momentum—implying that achievement (in education, creativity, or work) is less a product of compliance or rote ability than of an active desire to ask questions and explore. In this view, environments that reward inquiry—rather than merely correct answers—are more likely to produce meaningful accomplishment. The quote also aligns with a broader argument often associated with Robinson’s educational thinking: that cultivating intrinsic motivation and wonder is central to developing talent and innovation.
