人生没有如果,只有奋斗

    如果可以,我希望上天赐予我一场巨大的灾难,仅与我相关,而不会对任何人造成影响,心里的,肉身的。要么它将我彻底毁灭,让我崩溃,从此一蹶不振;要么我在痛苦中崛起,变得真正强大,而不是靠些哲学、励志性文字来抚慰满目疮痍的内心。因为我相信只有经过苦难的人才真正懂得苦难的价值。任何事物都有它的两面性。孔子也会犯错,杀人犯也有善良的时刻。挺过苦难的人内心绝对坚强,未来的路充满荆棘,但在他看来或许只是一块绊脚石,能够轻松而过,没有挺过的则连面对困难的勇气也已全然消失,只配被湮没在历史洪流。这种想法显然充满了赌博性,极大的,因为它的赌注是一个人的命运,如果可以,我很想一试,只可惜我从来不是一个人在生存,我的命运与许多人牵扯在一起,这辈子永远都割不断,也不能割,我的生存状态会对他们的情绪产生极其强烈的干扰,甚至如果我不幸崩溃了他们所经受的打击比我来得要严重千百倍,于是我不得不放弃这种设想。

    如果可以,我希望回光返照,我还是那个五岁的孩童,无忧无虑,天真烂漫,可以在妈妈的怀里尽情地撒娇,可以再村头池塘的浅水里尽情的嬉戏,可以用粉笔在房门上写着小舅教我的名字,哪怕外公骂了又骂,甚至和小伙伴打架打得鼻青脸肿,两分钟后一笑泯恩仇。只可惜真正的时光机还未诞生,现在没有,将来亦然。它只能在荧屏上显现它的神奇。

    如果可以,我甚至有时希望我是一个疯子,一个彻底的疯子,智商低于10,最好为0,蓬头垢面,穿着邋遢,吃着剩菜剩饭,喝着地沟水,时而狂吼,甚至裸奔,不用在意旁观者的眼光,不去对社会负责,天塌下来与我无关,依旧可以放声大笑,在自己的世界里,洒脱自在地做着梦,不复醒来,即使是在生命走向尽头的那一刻。只可惜这个条件未免太苛刻,上天不肯赐予我这般使命,就让它留在下辈子吧!

    如果可以…

    人生没有如果,我们在必然里活着。我相信每个人的宿命已定,那些曾经的,当前的,不久将来的行动不是在改变命运的进程,而是命运历程中必经的迹点。因此,我格外推崇一句话——世界上并无完全没有意义的生活,任何一种经历都可以转化为内在的财富。而且,这是最可靠的财富,因为没有人能从你那里夺走。曾经有个朋友跟我说过类似的话,多好啊!

    每个人的人生都以从母体呱呱坠地为起始,以两眼紧闭为终结,在某种程度上我们的人生是不是又充满着惊人的一致性。而怎样活着,则成为衡量一个人人生价值高低的标准。“人应该为活着本身而活着,而不是为活着之外的任何东西活着”。每个人的活法各不相同,既然如此,又何必羡慕别人的生活,活得那么劳累,徒增烦恼。

    既然年轻,就年轻地活着,不在于穿着如何光鲜亮丽,而在于是否有颗年轻的心。年轻人如果有使命,只能是奋斗;年轻人必然有使命,也只能是奋斗!

    Climate change has had a number of effects on cities around the world, including rising see levels. And, this has become an especially big problem for coastal cities. City officials must now prepare for higher tides on their coasts. The American city of Miami is one example. Located in South Florida, Miami is home to nearly 3 million people and billions of dollars in land and buildings.

    Miami is one of the cities in America most at risk for rising sea levels. The waterfront is central to Miami's culture and economy. But as the seas rise with climate change .the water will not stay put. Large parts of South Florida are in danger of being under water in the coming years. Across Biscayne Bay, the City of Miami Beach is making improvements - raising streets, adding water pumps and more.

    It is costing the city a lot of money. Local communities will spend 500 million dollars for the improvements. Thankfully, the residents, the folks that are paying the bill for this work, realize that the cost of doing nothing is much greater. A possibility officials are discussing with residents is for city to buy homes in some places where flooding has been a problem. The city would then turn that land into parks of grassland that could hold the water.

    Over time, the city may need to take bigger risks. Miami's future depends largely on how much, and how fast, the oceans rise.

    Caroline Lewis leads the climate activism group, the CLEO Institute. She says cities cannot avoid the need to move inland. But, she says,a well-planned withdrawal (撤退) could include measures to keep people safely in place for as long as possible. And, she says, the world could learn from such a model. In these two Florida cities built on wetlands, there remains a lot of hopefulness.
