Never stop learning, because the world never stops changing.

Scientific rigor must never be compromised by commercial pressures.

无产阶级，现今社会的最下层，如果不炸毁构成官方社会的整个上层，就不能抬起头来，挺起胸来。

Never stop learning, because life never stops teaching.

逆流而上。走另一条路。忽略传统智慧。如果其他人都在用一种方式做事，你很有可能通过走完全相反的方向找到你的利基。

The secret of change is to focus all of your energy, not on fighting the old, but on building the new.
