一个人的历史是自己书写的。要想让自己的一生过得有意义,就要有种精神,即献身精神。有了这种精神,什么困难都能克服。学习知识也要有这种精神。一个人不可能什么都懂。对新的知识,不懂就要虚心学习。虚心使人进步。可求教于国内外同行,甚至可以求教于自己的学生。时间不够怎么办?那就挤时间。我这几十年来几乎没有睡过午觉,每天中 One’s history is written by oneself. If you want to make your life worthwhile, you must have a spirit, that is, dedication. With this spirit, any difficulties can be overcome. This knowledge also needs to be learned. One cannot understand everything. If you do not understand new knowledge, you must learn modestly. Humility makes people progress. Can be consulted with colleagues at home and abroad, and can even ask their own students. What if you don’t have enough time? Then squeeze time. I have almost no naps in the past few decades.
