The real wisdom here isn't permission to be lazy—it's Einstein's insistence that your mind is too valuable for clerical work. He's drawing a distinction between *knowing facts* and *knowing how to think*, a difference most people conflate. When you stop spending mental energy on what your smartphone can retrieve in seconds, you free yourself to ask harder questions: why does this fact matter? How does it connect to what else I know? A surgeon doesn't waste cognitive space memorizing every drug interaction; she memorizes principles and knows where to verify specifics under pressure, reserving her actual intelligence for diagnosis and judgment.
