自信并非来自遗传，是需要后天学习的。这就意味着，你也可以充满自信。从现在、从这里开始。

自信首先从想法开始。你怎么样看待自己，很大程度影响了你觉得自己怎样。转而也影响了你说话、做事的方式。

没有你的同意，谁也无法将你看低一等。

充满自信的第一步是要开始自信地看待自己。注意自己的内心对话，注意你什么时候让消极和怀疑控制了自己的思想。

你周围的环境对你有着莫大的影响。你读的书，和你待在一起的人，你听的音乐都对你的思维方式、对自己的感觉以及对世界的看法产生影响。

during last weekend's Super Bowl, an ad from FedEx was the one many Americans found the most entertaining. It showed a caveman trying to use a pterodactyl for an express delivery, only to watch it be gobbled up on take-off by a tyrannosaur. What did the world do before FedEx, the ad inquired? It might have asked what on earth FedEx did before the arrival of online retailers, which would themselves be sunk without today's fast and efficient delivery firms.

Consumers and companies continue to flock in droves to the internet to buy and sell things, FedEx reported its busiest period ever last December, when it handled almost 9m packages in a single day. Online retailers also set new records in America. Excluding travel, some $ 82 billion was spent last year buying things over the internet, 24% more than in 2004, according to comScore Networks, which tracks consumer behaviour. Online sales of clothing, computer software, toys, and home and garden products were all up by more than 30%. And most of this stuff was either posted or delivered by parcel companies.

The boom is global, especially now that more companies are outsourcing production. It is becoming increasingly common for products to be delivered direct from factory to consumer. In one evening just before Christmas, a record 225,000 international express packages were handled by UPS at a giant new air-cargo hub, opened by the American logistics firm at Cologne airport in Germany. "The internet has had a profound effect on our business," says David Abney, UPS's international president. UPS now handles more than 14m packages worldwide every day.

It is striking that postal firms—once seen as obsolete because of the emergence of the internet—are now finding salvation from it. People are paying more bills online and sending more e-mails instead of letters, but most post offices are making up for the thanks to e-commerce. After four years of profits, the United States Postal Service has cleared its loss $11 billion of debt.

Firms such as Amazon and eBay have even helped make Britain's Royal Mail profitable. It needs to be: on January 1st, the Royal Mail lost its 350-year-old monopoly on carrying letters. It will face growing competition from rivals, such as Germany's Deutsche Post, which has expanded vigorously after partial privatization and now owns DHL, another big international delivery company.

Both post offices and express-delivery firms have developed a range of services to help e commerce and eBay's traders—who listed a colossal 1.9 billion items for sale last year. Among the most popular services are tracking numbers, which allow people to follow the progress of their deliveries on the internet.

How long will the boom continue? The parcel companies clearly see plenty of growth ahead—they are making big investments in new cargo hubs and aircraft. But in some areas the limits are already being tested. On February and Amazon, the best-known online retailer, announced a 17% increase in sales to almost $3 billion in its busy fourth quarter. But profits fell because of higher shipping costs.

Amazon has been subsidizing shipping to help boost its sales. Last year it introduced "Amazon Prime", which provides free shipping in return for a one-off payment. The tactic is "very expensive", Amazon's chief executive, Jeff Bezos, told analysts. But, he added, the early signs are that it does at least encourage people to buy more.

Yet internet-only e-tailers such as Amazon are also facing stiffer competition from bricks-and mortar stores improving their own online offers, including supermarket giants such as Wal-Mart. Some of these also offer "pick-up in-store" options for people buying online but wanting to avoid shipping costs or having to stay at home to take deliveries. Some of the parcels firms have been experimenti

easure without pain. The things that bring the greatest joy carry the greatest potential for loss the disappointment. Today, surrounded by promises of easy happiness, we need someone to tell us that it is ok not to be happy, that sadness makes happiness deeper. As the wine-connoisseur movie Sideways tells us, it is the kiss of decay and mortality that makes grape juice into Pinot Noir. We need art to tell us, as religion once did, Memento mori: remember that you will die, that everything ends, and that happiness comes not in denying this but in living with it. It's a message even more bitter than a clove cigarette, yet somehow, a breath of fresh air.

ory. In his astonishing address to the Young Men's Lyceum of Springfield, Ⅲ., on Jan. 27, 1838, on "the perpetuation of our political institutions", the 28-year-old Lincoln foresaw the inevitable rise in a modern democracy like ours of skepticism and worldliness. Indeed, he worried about the fate of free institutions in a maturing nation no longer shaped by a youthful, instinctive and (mostly) healthy patriotism. Such patriotism is natural in the early years after a revolutionary struggle for independence. To the generation that experienced the Revolution and the children of that generation, Lincoln explained, the events of the Revolution remained "living history", and those Americans retained an emotional attachment to the political institutions that had been created. But the living memories of the Revolution and the founding could no longer be counted on. Those memories "were a fortress of strength; but what invading foemen could never do, the silent artillery of time has done; the leveling of its walls". So, Lincoln concluded, the once mighty "pillars of the temple of liberty" that supported our political institutions were gone.

Lincoln implored his fellow citizens in 1838 to replace those old pillars with new ones constructed by "reason, cold, calculating, unimpassioned reason". He knew that such a recommendation—such a hope—was problematic. In politics, cold, calculating reason has its limits. In the event, it was Lincoln's foreboding of trouble, not his hope for renewal, that turned out to be correct. The nation held together for only one more generation. Twenty-three years after Lincoln's speech, the South seceded, and civil war came.

Lincoln managed, of course, in a supreme act of leadership, to win that war, preserve the union and end slavery. He was also able to interpret that war as producing a "new birth of freedom," explaining its extraordinary sacrifices in a way that provided a renewed basis for attachment to a nation conceived in liberty and dedicated to the proposition that all men are created equal. Perhaps the compromises made by the founding generation with the institution of slavery would have proved fatal in any case. Still, the fact is that the US was unable to perpetuate its political institutions peacefully after those who had lived through the Revolution died and even secondhand memories of America's founding faded.

Now we find ourselves in a situation oddly similar to the one Lincoln faced in 1838. Lincoln delivered his Lyceum Address 62 years after the Declaration of Independence. We are now the same time span from the end of World War II. Our victory in that war—followed by our willingness to quickly assume another set of burdens in the defense of freedom against another great tyranny— marked the beginning of the US's role as leader of the free world. Through all the ups and downs of the cold war and through the 1990s and this decade, the memories of World War II have sustained the US, as it did its duty in helping resist tyranny and expand the frontiers of freedom in the world.

The generation of World War II is mostly gone. The generation that directly heard tell of World War II from its parents is moving on. We have exhausted, so to speak, the moral capital of that war. Now we face challenges almost as daunting as those confronting the nation when Lincoln spoke. The perpetuation of freedom in the world is no more certain today than was the perpetuation of our free institutions then. Of course, we have the example of Lincoln to guide us. And Ferguson's wry and sardonic account of the ways we remember him is heartening and even inspiring, almost despite itself or despite ourselves. But the failures of leadership of the 1840s and 1850s should also chasten us. Nations don't always rise to the occasion. And the next generation can pay

不知哪是终点。有的人如游客，不急不慌，走走停停，看花开花落，看云卷云舒。有时也在风中走，雨中行，心却像张开的网，放过焦躁苦恼。人生之路谁不走?只是走路时别忽略了一路的良辰美景。

一个人工作的地方是小的，居住的家是小的，社交的圈子是小的，有的人就越来越不满这缺乏 变化的单调。有的人却总是怡然自得，随遇而安。世界浩渺，一个人只能居于一隅。比海洋大的是天空，比天空大的是心灵，因为这小小的心灵内住着一只时起时落的想象鸟。人生旅途上，有人背负着名利急急奔走，有人回归自然，飘逸而行。
