Wisdom isn't taught; it's not a science. Wisdom is a tattoo carved into the mind after a lifetime of failures and achievements.

The quote draws a sharp line between formal knowledge and lived understanding. By insisting wisdom “isn’t taught” and “is not a science,” it rejects the idea that wisdom can be transferred intact through instruction or reduced to rules. The metaphor of a “tattoo carved into the mind” suggests permanence, pain, and personal ownership: wisdom is inscribed through experience, especially through the friction of mistakes (“failures”) and the hard-won confirmation of what works (“achievements”). Its significance lies in reframing wisdom as cumulative and embodied—less a credential than a record of consequences that reshapes judgment over time.
