"Okay then, one more bit of advice before I drive you to the airport," the old man said, then paused. "Don't strive to learn anything at all. Instead, allow yourself to remember."
The grandson merely raised his eyebrows.
"What I mean is this," the old man continued. "The truest wisdom will never feel to you like something added, like something you're learning new. More often, it will be something that was already evident to common sense. It will always feel like you're remembering what you've known all along." He stood up, checking his pockets for car keys. "That's how you know it's the real thing. Wisdom will feel like something remembered."
