Teaching
Success is safest when enjoyed lightly, without letting it define your worth or distort your judgment.
Meaning
Detachment does not reject success. It prevents success from becoming identity, addiction, or blindness. Freedom means using gain wisely without becoming inwardly possessed by it.
Practical Application
After success, do one grounding act: serve quietly, return to discipline, or remember how much remains outside your control.
