人生支点

    ①人之所以能活着，是因为有许多支撑点，就像那火车之所以能在铁轨上前进，是因为有许多根枕木支撑着一样。

    ②只有一根枕木的铁路是没有的，只有一个支撑点的人生也是没有的。

    ③人生可以有很多支撑点，事业、升官、发财、爱情都可以成为人生某一个时期的支撑点，让你有滋有味地活下去，觉得天很蓝，草很绿，每个人的笑容都很美好。

    ④但我要告诉你，任何一个支撑点都不可能是永恒的，事业无穷尽，官做大了做久了也很乏味，钱挣得太多也是个累赘，山盟海誓的情人也终会有一天离你而去。

    ⑤所以我提出这样一个观点：泛点论。简而言之，即让你的人生多一些支撑点，其中的某一些点坍塌了，会有另一些支撑点支撑着你的人生构筑，让你在慢慢人生路上走下去。

    ⑥这就是老百姓所说的，别在一棵树上吊死，水路不通走旱路。

    ⑦谁也不可能把你的人生隧道构筑得那么牢固，因为这不单是你个人的问题，有些情况你不可能把握，你想得到的不一定都能得到，你期望得到的不一定都能成为现实。好些事和大环境有关，和人的主观能动性有关，更和一种叫做“数”的东西有关。所谓“数”，就是机遇。我欣赏一首流行歌曲里唱的：三分天注定，七分靠打拼。人生不打拼不可能成功，但你打足了七分，那三分老天不给你，你仍然不能得到一个完美的人生。

    ⑧炒股者都知道这样一句名言：不要把鸡蛋都放到一个筐里。甲筐让一个骑自行车的撞了，乙筐被冰雹砸了，丙筐还可以保住三分之一。再广而言之，甲筐里放草莓，乙筐里放枇杷，丙筐里放荔枝，则不管行情如何变化，你至少扳个平手，而不至于赔得吐血跳楼。

    ⑨人生亦如此。让你的人生多几个支点。

    It can be hard to meet people from another culture. From the beginning, people may send the wrong signal (信号). Or they may pay no attention to signals from another person who is trying to develop a relationship.
    Different cultures emphasize（强调）the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in “small talk”, usually over a glass of tea, before they do any job. In many European countries—like the UK or France—people find it easier to build up a lasting working relationship at restaurants rather than at the office.
    Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion; instead there was an uncomfortable silence. The people just looked at me all the time and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are not needed.
    Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share almost the same values; however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.
    People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural (多元文化) environment will offer a wonderful chance for us to learn from each other.
