"The past is always present in our lives, shaping our future."

Power is not a means; it is an end. One does not establish a dictatorship in order to safeguard a revolution; one makes the revolution in order to establish the dictatorship.

In the exploration of science, we must not only ask why but also why not.

如果你试图取得成就，就会遇到障碍。我遇到过；每个人都遇到过。但障碍不一定会阻止你。如果你遇到一堵墙，不要转身放弃。想办法爬过去，穿过它，或者绕过它。
