说勤

    俗话说：“一勤天下无难事。”唐代文学家韩愈说：“业精于勤荒于嬉。”

    勤，就是要珍惜时间，勤学习，勤思考，勤探索，勤实践。古今凡有建树者，无不成功于勤。

    勤出成果。马克思写《资本论》辛勤劳动40年。读了大量书籍，其中作过笔记的就有1500种以上；司马迁写《史记》从20岁就收集大量历史素材；我国当代数学家陈景润，翻阅了上千本有关资料，认真演算，取得了震惊世界的成就。

    勤出智慧。即使天资比较差，反应比较迟钝，只要勤，就可以变拙为巧。

    实践证明，一个人知识的多寡，成就的大小，关键在于勤的程度。只有勤奋者才能在无限的知识海洋里猎取到真智实才，开拓知识领域，使自己聪明。
