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 naveté. 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.把它稱作生活經歷也好或者艱苦的生活磨練也好，到了50歲時，我們都會意識到哪個決定是好的，哪個決定是滿意的，這些都是年輕天真的結果。但是無論你是堅定的相信“事出有因”，還是希望谷歌的天才們可以設計出時光機器，你可能已經從你的失敗中學習到了一些事情。
We asked our Huff/Post50 Facebook fanswhat they wish they'd known at 25 that they know now. Here's what they said every 20-something ought to know about life.我們詢問了50位Huff/Post Facebook上的粉絲，他們希望25歲時知道哪些現在已經知道的。下面是他們說的一些20多歲的人應該知道的關於生活的一些事情。
1. Speak up more.大膽說出自己的想法。
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****.俗話說的好，會叫的騾子多吃草。你是自己唯一併且最真實的.支持者，所以不要害怕支援你自己和說出你的想法，因為後悔可恥。
2. Know when to walk away.知道什麼時候離開。
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 realization, the more you can save yourself from making up for lost time.許多讀者聲稱離開，雖然它可能會是一個困難的決定，但是有時候也是你可以為自己做的最好的事情。並且你明白的越快，你免於彌補失去的時間就越多。
3. Save more money.存更多的錢。
Retirement is no joke, as you'll learn by 50. As you stare at the bleak reality of your 401K, you might find yourself counting every nickel and dime you wasted on frivolous 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.當你50歲時，你會學到退休不是開玩笑。當你註釋401K這一慘淡的現實時，你可能會發現自己計算浪費在零碎開支上的每一分錢。所以，自帶午餐，尋找街道停車位（或乘公共汽車），並且記住省一文就得一文，聽起來很棒。
