102 | 103 | 104 | 105 | 106 | 107 | 曾经有段时间，我有一个很执着的梦想，我要导演出一部空前绝后的句幕。不过现实无情地碾碎我的梦想，也同时将我推进了人生的低谷。 108 | 我开始思考，思想很多很多我以前总是回避的问题，在一次次思考中，我能感觉到我正在向一个陌生的地方走去，前途是光是暗也无法推测，我发现我在赌，赌注是一辈子的懊悔或是郁郁终生。 109 | 但当我看到阳光弥漫在我身边时，才发现以前的我是那么幼稚，我始终在找借口或不是借口的借口推卸掉与生俱来的责任，在光怪陆离的现实中午找个僻静的地方希望过云淡风轻的日子。我错了，我拥有足够的能力却不敢恣意妄为，我拥有惊人的天赋却畏惧这只是南柯一梦，或者这本来就是梦，醒来时却是了无痕迹和无休止的眷恋。 110 | 从前有个同学问我是不是幻想过一些特别的经历会降临到自己身上。 111 | 当时我只笑了笑，却不知道该怎么回答。 112 | 我想我是矛盾的，我认为我的存在与否关系到世间的万事万物，但我找不到足够的证据来证明我具有救世主的身份。因此我一度怀疑过我是不是生不逢时，或是天妒英才。 113 | 我在一次次轮回中等待着一个机会，也许是乱世，也许是太平，我没有所谓的一技之长，只有飞扬跋扈的骄傲和潮洗潮卷的胸怀。只有一笑置之的孤傲和白云苍狗的方式。 114 | 我想我不该妄自菲薄，甚至这是理所当然的不加半点修饰的顺其自然。 115 | 我很喜欢这样一句话：如果我将庸碌一生的话，地球将停止转动，地球停止转动了吗？没有，那我将不会庸碌一生。 116 | 在特定的时间，特定的环境，特定的地点，有个特定的人将主宰万事万物！ 117 | 天生我才必有用！ 118 | 经典的心照不宣，只可惜他的傲慢却没有足够的能力做基垫。 119 | 我想我是对的，注定的便是永远无法改变的，过去的只是匆匆一瞥，将来的只是白驹过隙，一次次的轮回换来的是麻木的循规蹈矩，所以世界需要那么一个人----改变。 120 | 过去亦空间空对月，茫茫鸿蒙无归处。 121 | 我如薏苡，为实。 122 | 众如佛珠，为空。 123 | 我为本，众为捧。 124 | 冥冥之间以无踪。 125 | 126 | 127 | 128 | 129 | 130 | 131
