These are the most difficult things I've learnt/am still learning.

這些是我已經學會的、還在學的最難的事情。

1.There are always going to be people who are smarter, better looking, more sociable, and just all around "better" than you. In fact, you'll learn there are LOTS of people who fit that description. To be happy, then, you have to learn to accept yourself and your shortcomings.

1.總會有比你聰明，比你好看，比你更擅長社交的人，到處都是比你好的人。事實上，許多人的確名副其實。開心點，你要學著接受自己和自己的缺點。

2.Success does indeed come from hard work. Hard work without talent doesn't ensure success, but talent without hard work ensures mediocrity.

2.成功的確需要努力。缺乏天賦只靠努力可能不會成功，但是只靠天賦不努力，注定碌碌無為。

3.It's unlikely you'll become anything close to your wildest ambitions, simply because you'll learn everyone has big ambitions, and there's only so many slots in this world.

3.你不太可能實現你最大的夢想，因為你會知道每個人都有大大的夢想，而世界上只有那么多位子。

4.Idealism aside, money = opportunity and therefore matters. Relationships and power matter more.

4.別太理想主義，錢就等于機會，所以錢很重要。人際關系和權力更重要。

5.Friendship isn't forever. Social and economic status does create divides and strains in even the oldest relationships.

5.友誼不是永遠的。即使在最長久的朋友之間，社會地位和經濟狀況也會造成你們之間的分歧和關系緊張。

6.Your parent(s) basically gave up their freedom to raise you, and deserve a medal. You know this because with only one job on your plate, you already have no time.

6.你的父母基本上是放棄了他們的自由來把你養大的，他們值得你的認可。這一點你應該很清楚，因為你現在只做一份工作都已經焦頭爛額了。

7.Adult life is about learning to live with ambiguity. Remember when you thought you'd have it all sorted out by 30? No. Whether it be your career, your relationships or your beliefs, you will always question whether you are making the right choices and will have to deal with regret.

7.成年人的生活是飄忽不定的。還記得你曾經想30歲的時候你就能安定下來嗎？不會的。這是否會是你的事業，你的愛人，你的信仰。你會經常問自己到底有沒有做出對的選擇，還有，如果你后悔了要怎么辦。

8.Metabolism slows.

8.新陳代謝會變慢。
