I think there is a second reason you are worried — related to but not entirely distinct from the first. You want to be happy. You have flocked to courses like “Positive Psychology” — Psych 1504 — and “The Science of Happiness” in search of tips. But how do we find happiness? I can offer one encouraging answer: get older. Turns out that survey data show older people — that is, my age — report themselves happier than do younger ones. But perhaps you don’t want to wait.

　　我认为你们之所以担忧有第二个原因——和第一个有关系但不是完全一样。你们希望过得幸福。你们蜂拥着去修“积极心理学”这门课——课程代号“心1504”——和“幸福的科学”这门课，不就是为了听点人生“小贴士”？可是，我们怎样才能获得幸福？在这儿，我可以提供一个启发性的答案：变老。调查数据显示年长的人——也就是我这把年纪的人——觉得自己比年轻人更幸福。不过，很可能你们没有人愿意去等着去看这个答案。

　　As I have listened to you talk about the choices ahead of you, I have heard you articulate your worries about the relationship of success and happiness — perhaps, more accurately, how to define success so that it yields and encompasses real happiness, not just money and prestige. The most remunerative choice, you fear, may not be the most meaningful and the most satisfying. But you wonder how you would ever survive as an artist or an actor or a public servant or a high school teacher? How would you ever figure out a path by which to make your way in journalism? Would you ever find a job as an English professor after you finished who knows how many years of graduate school and dissertation writing?

　　在聊天时我听过你们谈到你们目前所面临的选择，我听到你们一字一句地说出你们对于成功与幸福的关系的忧虑——也许，更精确地讲，怎样去定义成功才能使它具有或包含真正的幸福，而不仅仅是金钱和荣誉。你们害怕，报酬最丰厚的选择，也许不是最有价值的和最令人满意的选择。但是你们也担心，如果作为一个艺术家或是一个演员，一个人民公仆或是一个中学老师，该如何才能生存下去？然而，你们可曾想过，如果你的梦想是新闻业，怎样才能想出一条通往梦想的道路呢？难道你会在读了不知多少年研，写了不知多少毕业论文终于毕业后，找一个英语教授的工作？

　　The answer is: you won’t know till you try. But if you don’t try to do what you love — whether it is painting or biology or finance; if you don’t pursue what you think will be most meaningful, you will regret it. Life is long. There is always time for Plan B. But don’t begin with it.

　　答案是：你不试试就永远都不会知道。但如果你不试着去做自己热爱的事情，不管是玩泥巴还是生物还是金融，如果连你自己都不去追求你认为最有价值的事，你终将后悔。人生路漫漫，你总有时间去给自己留“后路”，但可别一开始就走“后路”。

　　I think of this as my parking space theory of career choice, and I have been sharing it with students for decades. Don’t park 20 blocks from your destination because you think you’ll never find a space. Go where you want to be and then circle back to where you have to be.

　　我把这叫做我的关于职业选择的“泊车”理论，几十年来我一直都在向学生们“兜售”我的这个理论。不要因为怕到了目的地找不到停车位而把车停在距离目的地20个路口的地方。直接到达你想去的地方，哪怕再绕回来停，你暂时停的地方只是你被迫停的地方。
