An American speaker once said: a two-hour speech can be delivered without preparation, a 15-minute speech requires a week of preparation, and a three-minute speech requires several weeks of preparation. Therefore, please allow me to refer to my own notes to bring you some reflection and inspiration. I also ask that you listen quietly without interruption. Thank you.
I have been contemplating a question: what is the ultimate meaning of life? Bi Shumin once stated that life itself is meaningless. You might wonder at this: how can life have no meaning? However, her point was that While life has no inherent meaning, you must establish a meaning for yourself. Upon closer reflection, this perspective holds more intellectual value than many grandiloquent claims. Returning to reality, as students, have we established our own sense of purpose?
Some might argue that they are defeated by the college entrance examination and that studying is merely a way to fulfill their parents' expectations. I feel sorrow for such individuals. They surrender their autonomy to their parents rather than taking control of their own hearts. While their lives may appear full on the surface, their inner worlds are empty—devoid of thought and pursuit. In my view, such a life is nothing more than a walking corpse.
一位美国演说家曾说过：两个小时的演讲可以无需准备，15分钟的演讲需要准备一周，而三分钟的演讲则需要准备数周。因此，请允许我参考一下自己撰写的文稿，希望能为大家带来一些思考与启迪。同时，请大家静心聆听，不要打断，谢谢。
我一直在思考一个问题：人生的意义究竟是什么？毕淑敏曾经说过，人生本身是没有意义的。听到这里，你可能会感到疑惑：人生怎么会没有意义呢？但她的意思是，人生本身并无预设的意义，但你应当为自己去确立一个意义。细究之下，这种观点比那些冠冕堂皇的论调更具有思考的价值。回到现实，作为学生，我们是否已经确立了属于自己的生命意义呢？
或许有人会说，我们正被高考所困，上学只是为了顺从父母的期望。对于这样的人，我会感到悲哀。他们将生活的自主权拱手让给了父母，而不是由自己掌控内心。这些人外表看起来过着充实的生活，内心却极度空虚——没有思考，没有追求。在我看来，这无异于一具行走的尸体。
