前不久，美国梭罗博物馆在互联网上搞了这么一个测试，题目是：你认为亨利•梭罗的一生很糟糕吗共有467 432人参加了测试，其结果是这样的：92.3%的人点击了“否”；5.6%的人点击了“是”；2.1%的人点击了“不清楚”。

这一结果非常出乎主办者的预料。大家都知道，梭罗毕业于哈佛大学，他没有像他的同学那样，去经商发财或走向政界成为明星，而是选择了瓦尔登湖。他在那儿搭起小木屋，开荒种地，写作看书，过着原始而简朴的生活。他在世44年，没有女人爱他，没有出版商赏识他，生前在许多事情上很少取得成功。他写作，静思，直到得肺病在康科德死去。

就是这样的一个人，世界上竟有那么多的人认为他的生活并不糟糕。难道这些点击者的生活还不如当时的梭罗吗显然不是， 因为从点击者选择的国旗来看，他们大多来自于西欧及北美。这些地方的人，即使是所谓的穷人，也远比当时的梭罗富裕。

那么是什么原因使他们羡慕起梭罗呢为了搞清楚其中的原因，梭罗博物馆在网上首先访问了一位商人。商人答：我从小就喜欢印象派大师凡•高的绘画，我的愿望就是做一位画家，可是为了挣钱，我却成了一位画商，现在我天天都有一种走错路的感觉。梭罗不一样，他喜爱大自然，他就义无反顾地走向了大自然，他应该是幸福的。

接着他们又访问了一位作家，作家说：我天生喜欢写作，现在我做了作家，我非常满意；梭罗也是这样，我想他的生活不会太糟糕。

后来他们又访问了其他一些人，比如银行的经理、饭店的厨师以及牧师、学生和政府的职员。其中的一位是这样给博物馆留言的：别说梭罗的生活，就是凡•高的生活，也比我现在的生活值得羡慕，因为他们没有违背上帝的意旨，他们都活在自己该活的领域，都做着自己天性中该做的事，他们是自己真正的主宰，而我却在为了过上某种更富裕的生活，在烦躁和不情愿中日复一日的忙碌。

我不知道，美国梭罗博物馆最终是否找到人们点击“否”的真正原因。我唯一清楚的是，在点击“否”的431 439票中，有我的一票。因为我一直认为，一种生活，只要适合自己，只要有自己喜欢的内容，就是最好的生活。

Roger Alvarez, 22, was one of the 52 percent of students who didn’t make it through his senior year at Manual Arts High School in Los Angeles.

He dropped out several years ago, but by the time he was in ninth grade, Alvarez says he already knew he wasn’t going to graduate.

“There’s a certain amount of knowledge you have to have when you enter in a specific grade, and I didn’t have it.” Alvarez says,“Every class I used to go in, I was like, ‘Do I know this? I don’t know this.’”

It was a shameful attitude, he tells his former English teacher, Antero Garcia, 29.

“You were determined to help me, but what was I willing to give? I could have actually tried.”

For his part, Garcia wants to know how he could have reached out to Alvarez better, but Alvarez says Garcia had always been helpful.

“I mean, you could cheer me up, and then I see other students doing way better,” Alvarez says,“So then, I get nervous. I get stuck, and then my motivation goes to the floor.” He felt the situation was hopeless.

“You talked to me like if I could do it, but inside me, I knew I couldn’t.” he tells Garcia,“I just didn’t want you to think that I’m…stupid.”

Now, school is a life tool that Alvarez says he’s missing—but his teacher isn’t to blame.

“Always, I just wanted you to know…you were a good teacher, and I always respected you.” he tells Garcia,“Some teachers, I felt like they only wanted to teach a certain group of people. But you looked at me and you paid attention.”

“Maybe it didn’t get me to graduate, but there’re a lot of teachers, they don’t take the time to take a look. And it was never your fault.”

Alvarez now works the night shift at a loading dock(码头). He still hopes to get his degree one day.
