What this quote means

Spencer warns against overprotection: if you prevent people from suffering the consequences of their mistakes, they never become wise. Folly (in the sense of imprudence) must sometimes clash with reality to learn. This thought resonates in education and relationships, where we often want to avoid all suffering, but experience is crucial.

How to apply it daily

Let someone (child, friend, colleague) face the consequences of their choice without intervening, so they can learn on their own.
