品味人生1、不管鸟的翅膀多么完美，如果不凭借空气，鸟就永远飞不到高空。
想象力是翅膀，客观实际是空气，只有两方面紧密结合，才能取得显着成绩。
2、想停下来深情地沉湎一番，怎奈行驶的船却没有铁锚;想回过头去重温旧梦，怎奈身后早已没有了归途。
因为时间的钟摆一刻也不曾停顿过，所以生命便赋予我们将在汹涌的大潮之中不停地颠簸。
3、真正痛苦的人，却在笑脸的背后，流着别人无法知道的眼泪，生活中我们笑得比谁都开心，可是当所有的人潮散去的时候，我们比谁都落寂。
4、温暖是飘飘洒洒的春雨;温暖是写在脸上的笑影;温暖是义无反顾的响应;温暖是一丝不苟的配合。
5、幸福，是一种人生的感悟，一种个人的体验。
也许，幸福是你风尘仆仆走进家门时亲切的笑脸;也许，幸福是你卧病床上百无聊赖时温馨的问候;也许，幸福是你屡遭挫折心灰意冷时劝慰的话语;也许，幸福是你历经艰辛获得成功时赞赏的掌声。
关键的是，你要有一副热爱生活的心肠，要有一个积极奋进的目标，要有一种矢志不渝的追求。
这样，你才能感受到幸福。
6、母爱是迷惘时苦口婆心的规劝;母爱是远行时一声殷切的叮咛;母爱是孤苦无助时慈祥的微笑。
7、淡淡素笺，浓浓墨韵，典雅的文字，浸染尘世情怀;悠悠岁月，袅袅茶香，别致的杯盏，盛满诗样芳华;云淡风轻，捧茗品文，灵动的音符，吟唱温馨暖语;春花秋月，红尘阡陌，放飞的思绪，漫过四季如歌。
读一段美文，品一盏香茗，听一曲琴音，拾一抹心情。
8、尘缘飞花，人去楼空，梦里花落为谁痛?顾眸流盼，几许痴缠。
把自己揉入了轮回里，忆起，在曾相逢的梦里;别离，在泪眼迷朦的花落间;心碎，在指尖的苍白中;淡落，在亘古的残梦中。
在夜莺凄凉的叹息里，让片片细腻的柔情，哽咽失语在暗夜的诗句里。
9、用不朽的“人”字支撑起来的美好风景，既有“虽体解吾犹未变兮”的执着吟哦，也有“我辈岂是蓬蒿人”的跌宕胸怀;既有“我以我血荐轩辕”的崇高追求，也有“敢教日月换新天”的豪放气魄。
33 我是一只蜜蜂，在祖国的花园里，飞来飞去，不知疲倦地为祖国酿制甘甜的蜂蜜;我是一只紫燕，在祖国的蓝天上，穿越千家万户，向祖国向人民报告春的信息;我是一滴雨点，在祖国的原野上，从天而降，滋润干渴的禾苗;我是一株青松，在祖国的边疆，傲然屹立，显示出庄严的身姿。
