多行不义，必自毙。——《左传》 世间最容易的事是坚持，最难的事也是坚持。要记住，坚持到底就是胜利。 并非神仙才能烧陶器，有志的人总可以学得精手艺。 困难越大，荣耀也越大。 命运之神关上一道门，必定会打开另一扇窗。 第一个青春是上帝给的；第二个的青春是靠自己努力的。 人生最大的挑战没过于战胜自己！ 人总是在失去了才知道珍惜！ 相信就是强大，怀疑只会抑制能力，而信仰就是力量。 有志者自有千方百计，无志者只感千难万难。 宁可失败在你喜欢的事情上，也不要成功在你所憎恶的事情上。 多行不义，必自毙。——《左传》 漫无目的的生活就像出海航行而没有指南针。 走得最慢的人，只要他不丧失目标，也比漫无目的地徘徊的人走得快。 树立必信的信念，不要轻易说“我不行”。志在成功，你才能成功。 一帆风顺，并不等于行驶的是一条平坦的航线。 如果要给美好人生一个定义，那就是惬意。如果要给惬意一个定义，那就是三五知己、谈笑风生。 每一个成功者都有一个开始。勇于开始，才能找到成功的路。 如果要飞得高，就该把地平线忘掉。 少一点预设的期待，那份对人的关怀会更自在。
