The only limit to our realization of tomorrow is our doubts of today.

最大的风险是不冒任何风险。在一个快速变化的世界里，唯一注定失败的策略就是不冒险。

如果我能用语言表达，就没有理由画画了。

Every seed planted today is an investment in tomorrow's food supply.

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.

语言是心灵的声音。
