And you reach a wall, a barrier. What do you do? Well, there are many things that you can do when you reach that wall.
你遇到一道墻,一個障礙物,你會怎么做?遇到那道墻時你可以有很多應對方法
And the wall is long and high. One way is to say, "OK, pity" and turn around. In other words, avoid that wall. Another thing we can do is take out our sledgehammer and try to break it down. Another thing that we can do before we do any of the other things is take our knapsack and throw it over the wall.
那墻又高又長,其中一種做法是“太可惜了”,然后調頭走。也就是說,避開那道墻。另一種方法是,拿出錘子試著把它敲碎。還有另一種方法是,把背包扔過墻去

Take our knapsack and simply throw it over the wall. Why? Because the necessity is the mother of inventions. I need my knapsack to continue. I need my knapsack. I want it. And now it's over the wall. I have no choice. But to get over that wall, whether it's by breaking it down, whether it's by finding a way around it, under it or over it.
把背包扔過墻去,為什么?因為必需品是發明創造的源泉。我需要背包來繼續,需要我的背包,我需要它,而現在它在墻的另一邊,我別無選擇了。但要越過這道墻,要么把它敲碎,要么找一條路繞過它,從下方或是上方
But suddenly, I will come up with solutions that I have not seen before and this is how it works. It's remarkable- how it works- for the exact same reason that when you declare a goal such as "I want to buy a computer". Suddenly you see computer ads all around you, whereas before you didn't see computer ads.
突然間,我會想出幾個辦法,這些辦法都是我之前沒想到的。目標起的作用十分顯著,而出于同一個原因。當你宣告一個目標,例如“我想買電腦”,那你就會發現到處都是電腦廣告,你以前從沒在這些地方看過電腦廣告
