明朝未及，我只有过好每一个今天，唯一的今天。
昨日的明天是今天。明天的昨日是今天。为什么要计较于过去呢（先别急着纠正我的错误，你确实可以在评判过去中学到许多）。但是我发现有的人过分地瞻前顾后了。为 何不想想“现在”呢？为何不及时行乐呢？如果你的回答是“不”，那么是时候该重新考虑一下了。成功的最大障碍是惧怕失败。这些句子都教育我们：不要惧怕失败。如 果你失败了他不会坐下来说：“靠，我真失败，我放弃。”并且不是一个婴儿会如此做，他们都会反反复复，一次一次地尝试。如果一条路走不通，那就走走其他途径，不 断尝试。惧怕失败仅仅是社会导致的一种品质，没有人生来害怕失败，记住这一点。宁愿做事而犯错，也不要为了不犯错而什么都不做。不一定要等到时机完全成熟才动手。 开头也许艰难，但是随着时间的流逝，你会渐渐熟悉你的事业。世上往往没有完美的时机，所以当你觉得做某事还不是时候，先做起来再说吧。喜欢追梦的人，切记不要被 梦想主宰；善于谋划的人，切记空想达不到目标；拥有实干精神的人，切记选对方向比努力做事重要。太阳不会因为你的失意，明天不再升起；月亮不会因为你的抱怨，今 晚不再降落。蒙住自己的眼睛，不等于世界就漆黑一团；蒙住别人的眼睛，不等于光明就属于自己！鱼搅不浑大海，雾压不倒高山，雷声叫不倒山岗，扇子驱不散大雾。鹿 的脖子再长，总高不过它的脑袋。人的脚指头再长，也长不过他的脚板。人的行动再快也快不过思想！以前认为水不可能倒流，那是还没有找到发明抽水机的方法；现在认 为太阳不可能从西边出来，这是还没住到太阳从西边出来的星球上。这个世界只有想不到的，没有做不到的！不是井里没有水，而是挖的不够深；不是成功来的慢，而是放 弃速度快。得到一件东西需要智慧，放弃一样东西则需要勇气！终而复始，日月是也。死而复生，四时是也。奇正相生，循环无端，涨跌相生，循环无端，涨跌相生，循环 无穷。机遇孕育着挑战，挑战中孕育着机遇，这是千古验证了的定律！种子放在水泥地板上会被晒死，种子放在水里会被淹死，种子放到肥沃的土壤里就生根发芽结果。选

There exist so many planets in the universe, among which the earth is the most important.
How did the earth and life come into existence?

人生终有许多选择。每一步都要慎重。但是一次选择不能决定一切。不要犹豫，作出选择就不要后悔。只要我们能不屈不挠地奋斗，胜利就 在前方。 千万人的失败，都有是失败在做事不彻底，往往做到离成功只差一步就终止不做了。 不论你在什么时候开始，重要的是开始之后就不要停止。 人惟患无志，有志无有不成者。 过去不等于未来。 其实世界上没有那么多的如果，有时候，我们一瞬间失去的东西就是永恒。 最好的投资就是投资自己，因为这是你唯一能确定只赚不赔的投资。 立志是事业的大门，工作是登门入室的旅程。 学习不但意味着接受新知识，同时还要修正错误乃至对错误的认识。 只有不想做的，没有做不到的。 一个华丽短暂的梦，一个残酷漫长的现实。 壮志与毅力是事业的双翼。 学习是苦根上长出来的甜果。 很多时候，感情往往能经得起风雨，却经不起平淡；友情往往能经得起平淡，却经不起风雨。 再高深的学问也是从字母学起的。
