——知乎？世界文化真相似
20几岁到三十几岁，对于全世界的人来说都是人生中重要的10年（21-31岁，29-39岁）。也可以说从20岁到40岁是一个人的黄金二十年。成年人的世界里，没有哪个人是容易的，学会坚忍，学会释怀，这个阶段就像哑巴吃黄连，有苦说不出。“洋知乎”Quora上面有一个热门问题叫：
What are the most difficult and useful things people have to learn in their 20s？
20几岁的人最该学也最难学的是什么？
下面7个回答好评最多，你会发现，世界文化各异，但有些核心东西惊人的相似。哪怕就是过了黄金20年，对照自己的认识，什么时候学习都不晚，活到老，学到老嘛！希望能在这重要的当下时节帮到您。
1.以后的人生并不是单线竞争
There are always going to be people who are smarter, better looking, more sociable, and just all around "better" than you.
总会有比你聪明，比你好看，比你更擅长社交的人。人外有人，天外有天。
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.
事实上，许多人的确名副其实。开心点，你要学着接受自己和自己的缺点。

别把“努力”和“天赋”分开来看
Success does indeed come from hard work.
成功的确需要努力。
Hard work without talent doesn't ensure success, but talent without hard work ensures mediocrity.
缺乏天赋只靠努力可能不会成功，但是只靠天赋不努力，注定碌碌无为。
3
有志者，并非事竟成
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.
你不太可能实现你最大的梦想，因为你会知道每个人都有大大的梦想，而世界上只有那么多位子。

重新认识金钱&人际关系
Idealism aside, money = opportunity and therefore matters.
别太理想主义，钱就等于机会，所以钱很重要。
Relationships and power matter more.
人际关系和权力更重要。

你的生活终究是自己一个人的
Friendship isn't forever.
友谊不是永远的。
Social and economic status does create divides and strains in even the oldest relationships.
即使在最长久的朋友之间，社会地位和经济状况也会造成你们之间的分歧和关系紧张。

父母可能没做对，但他们努力了
Your parent(s) basically gave up their freedom to raise you, and deserve a medal.
你的父母基本上是放弃了他们的自由来把你养大的，他们值得你的认可。
You know this because with only one job on your plate, you already have no time.
这一点你应该很清楚，因为你现在只做一份工作都已经焦头烂额了。
7
总会有新问题
Adult life is about learning to live with ambiguity.
成年人的生活是飘忽不定的。
Remember when you thought you'd have it all sorted out by 30?
还记得你曾经想30岁的时候你就能完全搞定自己的生活吗？
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.
不会的，不管是事业、情感还是价值观，你始终都会质疑自己到底有没有做出对的选择，而且将一直面对自己的遗憾。
