永不言败，是成功者的最佳品格。 再好的种子，不播种下去，也结不出丰硕的果实。 人总是珍惜未得到的，而遗忘了所拥有的。 别太注重自己和他人的长相，能力没写在脸上。如果你不是靠脸吃饭，关注长相有个屁用！ 活着不是靠泪水搏取同情，而是靠汗水获得掌声。 失败的定义：什么都要做，什么都在做，却从未做完过，也未做好过。 当你能梦的时候就不要放弃梦。 家！甜蜜的家！！天下最美好的莫过于家！ 家！甜蜜的家！！天下最美好的莫过于家！ 不要太在乎自己的长相，因为能力不会写在脸上。 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。 士搏出惊涛骇流而不沉沦，懦夫在风平浪静也会溺水。 没有了爱的语言，所有的文字都是乏味的。 一日不读口生，一日不写手生。 每天告诉自己一次，“我真的很不错”。 站在巨人的肩上是为了超过巨人。 因为一无所有这才是拼下去的理由。 我在奋斗在坚持在拼搏在努力你要等。 当你能梦的时候就不要放弃梦。 假如你从来未曾害怕受窘受伤害，那就是你从来没有冒过险。
