It is impossible for a person to learn what they thinks they already knows - Epictetus.
We must not make the mistake of being so consumed by our own "knowledge" that we forget to learn. We must admit that we don't know everything, and must always have a mindset of learning. Through this, we can develop our knowledge and expand our horizons.
Remember to always keep an empty cup, because this is what helps us navigate life.
Happy listening!
