What this quote means

This rhetorical question underscores humility before the vastness of knowledge. No one, even the most learned, can know everything. It reminds us that knowledge is an endless ocean, and each answer opens new questions. It's an invitation to stay curious and acknowledge the limits of our understanding.

How to apply it daily

Identify a topic you think you know well and ask yourself a question you can't answer. Seek the answer to broaden your horizons.
