人生应为生而食，不应为食而生。
One should eat to live，not live to eat.
快乐的唯一方法是热爱你所做的事情。
On the path of science, there are no smooth roads to take; only those who are not afraid of hard work and climb the steep mountain paths have the hope of reaching the glorious summit.
实现明天的唯一限制是我们今天的疑虑。
"Courage is not the absence of fear, but the triumph over it."
