“All the knowledge in the world cannot help you to find happiness, if you don't know yourself.”

Knowledge becomes useful through the life of the person who holds it. Without knowing what matters, what brings joy, or what kind of life feels true, even wise choices can lead somewhere empty. Self-knowledge gives other understanding a centre. It helps a person tell the difference between an opportunity that fits and one that merely looks impressive from the outside. What others call a loss may then protect a deeper happiness.

Life can contain everything people are expected to want and still feel like nothing to the person living it. Knowing oneself does not remove every hard choice. It makes those choices readable, because there is a clearer sense of who must live with the result.
