永远不要停止学习,因为世界永远不会停止变化。
教师必须为形成较好人类而献出一切。
Time is your friend; impulse is your enemy.
People are curious. A few people are. They will be driven to find things out, even trivial things. They will put things together, knowing all along that they may be mistaken.
The biggest risk is not taking any risk.
