If you live long enough, you’ll make mistakes. But if you learn from them, you’ll be a better person. It’s how you handle adversity, not how it affects you. The main thing is never quit, never quit, never quit.

The quotation frames error as an inevitable byproduct of longevity and action, shifting the moral emphasis from avoiding mistakes to extracting instruction from them. It proposes a resilience ethic: adversity is not decisive in itself; character is revealed in one’s response—learning, adapting, and persisting. The closing refrain (“never quit”) turns the reflection into a practical maxim, suggesting that endurance is the enabling condition for growth and eventual achievement. In a Clinton context, the sentiment also reads as a public-facing philosophy of recovery after setbacks: personal improvement and continued effort are presented as the proper answer to failure rather than withdrawal or self-pity.
