Call it life experience or the school of hard knocks, by 50 we all have the hindsight to know which decisions were good ones and which decisions were, well, a result of youthful naïveté. But whether you're a firm believer in "everything happens for a reason" or you wish the brains at Google would develop a time machine, you've probably learned a thing or two from your failures.

把它称作生活经历也好或者艰苦的生活磨练也好，到了50岁时，我们都会意识到哪个决定是好的，哪个决定是满意的，这些都是年轻天真的结果。但是无论你是坚定的相信“事出有因”，还是希望谷歌的天才们可以设计出时光机器，你可能已经从你的失败中学习到了一些事情。

We asked our Huff/Post50 Facebook fans what they wish they'd known at 25 that they know now. Here's what they said every 20-something ought to know about life.

我们询问了50位Huff/Post Facebook上的粉丝，他们希望25岁时知道哪些现在已经知道的。下面是他们说的一些20多岁的人应该知道的关于生活的一些事情。

1. Speak up more.大胆说出自己的想法。

As the saying goes, it's the squeaky wheel that gets the grease. You are your one and only true advocate, so never be afraid to stand up for yourself and speak your mind, because regret's a b****.

俗话说的好，会叫的骡子多吃草。你是自己唯一并且最真实的支持者，所以不要害怕支持你自己和说出你的想法，因为后悔可耻。

2. Know when to walk away.知道什么时候离开。

Many readers voiced that walking away, while it may be a difficult decision, is sometimes the best thing you can do for yourself. And the quicker you can come to this realization¹, the more you can save yourself from making up for lost time.

许多读者声称离开，虽然它可能会是一个困难的决定，但是有时候也是你可以为自己做的最好的事情。并且你明白的越快，你免于弥补失去的时间就越多。

3. Save more money.存更多的钱。

Retirement² is no joke, as you'll learn by 50. As you stare at the bleak³ reality of your 401K, you might find yourself counting every nickel and dime⁴ you wasted on frivolous⁵ expenses. So pack your lunch, find street parking (or take the bus) and remember that a penny saved is a penny earned, as cheesy as it sounds.

当你50岁时，你会学到退休不是开玩笑。当你注释401K这一惨淡的现实时，你可能会发现自己计算浪费在零碎开支上的每一分钱。所以，自带午餐，寻找街道停车位（或乘公共汽车），并且记住省一文就得一文，听起来很棒。

4. Re-think a college major.重新思考一下大学专业。

A few readers mentioned how they wish they'd re-considered their choice of college major, or even thought twice before dropping out.

少数读者提到，他们希望重新考虑选择大学专业，或者在退学前甚至再三考虑。

5. Travel more.多旅行。

You're only young once. So before you get tied down by responsibilities of a mortgage, a spouse⁶ and kids, it's a good idea to explore the world and all it has to offer (as long as it doesn't break the bank!). Consider working abroad. Visit the city you dream about all day. Just go somewhere that will make you look up and around rather than down at your smartphone.

你只会年轻一次。所以，在你被抵押贷款、配偶和孩子的责任束缚前，探险世界和它提供的一切是个不错的主意（只要它不会倾家荡产！）。考虑到国外工作。参观你整天梦想的城市。去一些可以让你观看周围一切的地方，而不是在智能手机上下载的。

6. Incur⁷ less debt.借较少的债务。

Don't buy things you don't need and think long and hard before getting a credit card. No matter what they tell you, it's not free money, and no matter how high the limit, you shouldn't go blow it all on designer duds and a fancy vacation. Debt sucks in any form. Instead, focus on building a solid credit history and credit score so you can finally nab a killer⁸ interest rate when you go sign a mortgage.

不要买你不需要的东西，在申请信用卡前长时间沉入思考下。无论他们告诉你什么，它不是免费的，并且无论她告诉你最高限额是多少，你不应该搞砸所有设计师设计的衣服和高档度假。债务有各种形式。你可以专注于建立一个稳固的信用档案和信用分数，所以当你去签署抵押贷款时，你能够得到最低利率。

7. Wear more sunscreen.多涂防晒霜。

Basking⁹ in the rays may pay off in the short run with a glistening¹⁰ tan, but in the long run it leads to age spots, wrinkling and sagging¹¹ of the skin. So grab the SPF year-round, reach for self-tanner or just embrace your skin tone ·for what it is.

沐浴在阳光中可能短期类会让你拥有闪亮棕褐色皮肤，但是从长远来看，它会导致老年斑、皱纹和下垂的皮肤。所以全年涂抹防晒霜，获得古铜肤色或者欣然接受你本身的肤色。

8. Think carefully before marriage.结婚前考虑清楚。

Several readers voiced they would have waited to get married. One reader said she would have waited until at least 30. While there's no hard and fast rule everyone can apply, it's sound advice at any age -- to think carefully before you wed¹².

一些读者表示他们会等晚点结婚。一个读者说她会等到至少30岁才结婚。虽然没有每个人都适用的硬性规定，但是这是对处任何年龄的人的忠告--在你结婚前仔细考虑清楚。

9. Slow down.慢一点。

Too many of us waste precious moments because we're too busy connected to our digital devices or on social media or worrying about the next career move. Life is short. Savor¹³ it. We think reader Trisha C Mokoshsq put it perfectly¹⁴: "I would not have been so driven to be successful and work 80 hours a week to make partner all those years. I would have lingered. I would have defined myself by more than what I did for a living."

我们很多人浪费了很多宝贵的时间，因为我们忙于处理数字设备或社交媒体或担忧下次的事业变动。生命短暂。享受它。我认为读者Trisha C Mokoshsq说的很好：“我不会如此想要成功，所有的这些年，每周工作80个小时广交合作伙伴。我会徘徊逗留。我会重新定义我要做的事情，而不仅仅是为了生存。”

10. Get a better education.得到更好的教育。

As the saying goes, nobody can take your accomplishments¹⁵ away from you. Education is one of those accomplishments. Many readers wished they would have either gone to or stuck to college. Whether it's to land you the career of your dreams, or to meet people from different walks of life or to learn to see things a little differently, education is always a good choice, whatever form it takes.

俗话说得好，没有人可以带走你的成就。教育就是这些成就之一。许多读者希望他们可以读大学或坚持读完大学。无论它是让你拥有梦想的事业，还是见来自各行各业的人，还是学习看待事情的见解有些不一样，教育总是一个不错的选择，无论它采取什么形式。

11. Consider health issues.考虑健康问题。

By 25 you might have noticed your metabolism¹⁶ slowing down. But looking after yourself as you age is about more than just quitting your pizza-a-day diet for vanity. It's about creating habits (and breaking bad ones) that will lead to a long life in which you're healthy enough to do everything you want to do. So quit smoking or cut back on the alcohol. As many of you said, little changes can lead to big benefits in the long run.

到了25岁，你可能会注意到你的新陈代谢变慢了。但是在这个年纪照顾好自己，不仅仅是为了虚荣抛弃你每天吃披萨的饮食习惯。它需要培养让你活的更久的习惯（打破坏习惯），这样你就足够健康可以做你想要做的一切事情。所以戒烟或少喝酒。正如许多人说的，从长远来看 ，小的变化可以带来大的效益。
