The most powerful motivator is not money. It’s the opportunity to learn, grow in responsibilities, contribute to others, and be recognized for achievements.

The deepest need of man is the need to overcome his separateness, to leave the prison of his aloneness.

你人生的热情应该恰到好处；但你的人生目标应该超越自己。为那些远比你更宏大的东西而工作。
