知识最大的敌人不是无知，而是知识的幻觉。
"The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge."
The challenge of leadership is to be strong, but not rude; be kind, but not weak; be bold, but not bully; be thoughtful, but not lazy; be humble, but not timid; be proud, but not arrogant; have humor, but without folly.
