Universally feared and loathed by any writer who's taken a Fiction 101 class, cliches are, by definition, phrases so overused that they've become virtually meaningless. We tend to dismiss these groan-inducing turns of phrase as hackneyed and outdated, and often for good reason.


But while the value of many of the most cliched proverbs and idioms is undeniably questionable ("Familiarity breeds contempt" and "No pain, no gain," for starters), others have stood the test of time because they do reveal certain universal truths about human nature.


Here are 10 pieces of time-worn folk wisdom that can still tell us something important about who we are.


"People in glass houses shouldn't throw stones."


look out window


We've all used (or at least heard) the "people in glass houses" idiom to describe someone who criticizes others for faults that they themselves possess. We may call it hypocrisy, but it's actually a common defense mechanism[1] : What we reject in others is precisely what we reject in ourselves. It's what life coach Sharon Lamm calls[2] "You spot it, you got it" syndrome.


The cliche is also supported by Freudian psychoanalysis[3] . In 1890, Freud first outlined his theory of psychological projection, which suggests that we unconsciously reject our own "unacceptable" habits and behaviors by ascribing them to people and objects outside of ourselves.


"Look not to the faults of others, nor to their omissions and commissions," the Buddha once advised. "But rather look to your own acts, to what you have done and left undone."


"Laughter is the best medicine."


happiness


The healing powers of laughter are no joke. Small studies have linked laughter with lower stress levels[4] , reduced blood sugar levels in those with diabetes[5] and improved sleep quality[6] .


Regularly cracking up can even help you to live longer. In a 2008 WebMD survey of 100 centenarians[7] , laughter was the third-most important aspect of healthy aging: 88 percent of those who lived past the age of 100 said laughter and having a sense of humor were "very important" to aging well.


"The early bird catches the worm."

Although there are many cases of wildly successful night owls[8] , research has linked rising early with success and positive personality traits. One study found that college students who identified as morning people had significantly higher average GPAs than those who liked to stay up late (3.5 vs. 2.5), and a Harvard biologist found that early risers are more likely to have proactive personality traits, Forbes reports[9] . Many of the world's most influential CEOs say that they wake up by 6 a.m.[10] (which we wouldn't necessarily recommend, unless you're hitting the hay by 10 p.m.), proving that, as Benjamin Franklin famously said[11] , "Early to bed and early to rise, makes a man healthy, wealthy, and wise."


"The grass is always greener on the other side of the fence."


grass is always greener


The cautionary "grass is always greener" proverb may be the most time-worn of all cliches, and for good reason. Part of the human experience -- and a universal cause of unhappiness -- is the idealization and desire for what we can't have[12] . Sometimes we want things for the sole reason that we don't already have them, and once we do, we may not even want them any more.


But research says appreciating what you already have could make you happier. Scientists have linked an attitude of thankfulness and gratitude with better health and well-being[13] .


"Old habits die hard."


sugar diet


Aristotle famously said, "We are what we repeatedly do. Excellence, then, is not an act but a habit." It's true: Most of us have an extraordinarily difficult time trying to change our habits or create new ones. And research backs that up.


“If you do something over and over, and dopamine is there when you’re doing it, that strengthens the habit even more. When you’re not doing those things, dopamine creates the craving to do it again,” University of Texas neurobiologist Dr. Russell Poldrack tells the National Institutes of Health[14] . “This explains why some people crave drugs, even if the drug no longer makes them feel particularly good once they take it.”


"A picture is worth a thousand words."


picasso guernica


Images may in fact be more powerful than words. Images are easier for most people to remember -- psychologists have found[15] that pictures are recalled more easily than words on recognition tests -- and an estimated 65 percent [16] of the population are visual learners, meaning that they process information best with their eyes (which could be an image or written text). A single image has the power to encompass a complex idea or theme, like Picasso's Guernica (pictured above), which made one of the most powerful political statements of World War II, without using any words at all.


The power of images is particularly evident in advertising: A study published earlier this year in the journal PLOS One found that when it comes to anti-smoking ads[17] , images are more effective than words alone in warning people about the dangers of smoking.


"A watched pot never boils."


water boil pot


Psychologically speaking, waiting makes our experience of time slow down, which means when you're standing in line at the airport or waiting for a tardy friend to meet you for dinner, the minutes seem to drag on. In other words, it feels like the watched pot will never boil.


"Occupied time (walking to baggage claim) feels shorter than unoccupied time (standing at the carousel)," Alex Stone wrote in a 2012 New York Times article, "Why Waiting in Line is Torture."[18] "Research on queuing has shown that, on average, people overestimate how long they’ve waited in a line by about 36 percent."


"Beauty is in the eye of the beholder."


eye beauty


Since the ancient Greeks, philosophers have argued over the nature of beauty. They've generally come to the conclusion that our experience of beauty is subjective -- and there's no scientific standard to determine what qualities are inherently "beautiful." Although cognitive scientists have pinpointed[19] certain female facial features that we tend to deem more attractive (largely having to do with symmetry and ratios), beauty is still something that, in most cases, can't be agreed upon.


Look no further than shifting cultural beauty standards through history[20] , which have changed drastically from the "Rubenesque" ideal of the 17th century to the Twiggy figure of the 1960s.


"When the going gets tough, the tough get going."


resilience


This classic proverb points toward the power of psychological resilience[21] . In the face of challenges, resilient (or "tough") people rise up -- no matter how many times they've fallen down in the past -- to face life's difficulties with courage and conviction. And the more often people rise to challenges, the tougher they become.


As Norman E. Rosenthal, author of The Gift Of Adversity, puts it[22] , "Hardship toughens us, deepens our understanding of life and of ourselves and, in the end, leaves us with hard-earned wisdom."

  • David Brooks


    New York Times columnist David Brooks got an unlikely start to his career as a writer, author and political commentator. He began writing a humor column for the school paper in his junior year at the University of Chicago. During his senior year, when he learned that author William F. Buckley was visiting the campus, Brooks sent the author a parody of his memoir, <em>Overdrive</em>, <a href="http://nymag.com/news/media/67010/index4.html" target="_blank">New York magazine reports</a>. Brooks added a note that read: “Some would say I’m envious of Mr. Buckley. But if truth be known, I just want a job and have a peculiar way of asking. So how about it, Billy? Can you spare a dime?” Buckley announced during his lecture in Chicago the next week, "David Brooks, if you’re in the audience, I’d like to give you a job." Unfortunately, Brooks wasn't there -- he had been selected to participate in a debate tournament in California that day -- but he quickly launched a successful career in journalism after college nonetheless.




  • Sally Field


    Sally Field may be an Oscar-winning actress, but she still had to fight to land a role she knew was meant for her, playing Mary Todd Lincoln, Abraham Lincoln's wife, in the 2012 film, "Lincoln." The actress fought hard to convince director Steven Spielberg (who originally <a href="http://www.youtube.com/watch?v=JVizVfzSqEI" target="_blank">said</a> he knew she was "not right") and leading man Daniel Day-Lewis that she was the one for the part. Following an initial screen test -- after which Spielberg refused her for the role -- Field convinced Day-Lewis to fly to Los Angeles from Ireland for the day to improv with her in full costume for Spielberg. She nailed it -- and the rest is history. "To actually become Mary, I had to demand that they didn't walk away," <a href="http://www.youtube.com/watch?v=5uBqUM6RfjQ" target="_blank">Field told Good Morning America</a>.




  • Anderson Cooper


    Anderson Cooper <a href="http://www.biography.com/people/anderson-cooper-20851303" target="_blank">began his media career</a> as a fact-checker for Channel One, which produces news shows to be broadcast in schools. But the ambitious Cooper -- who had just received his degree in political science from Yale -- got bored with the position pretty quickly. Rather than resigning himself to the daily grind, Cooper took his video camera to Southeast Asia, where he filmed scenes of strife in Myanmar and then parts of Africa. The stunt quickly earned him the position of chief international correspondent for Channel One, and ultimately caught the attention of ABC News, where he landed his first job as an anchor.




  • Michael Lewis


    Best-selling author and business journalist Michael Lewis has made a career out of uncovering the dark secrets of Wall Street. But he wasn't always getting bylines on cover stories for Vanity Fair and The New York Times -- Lewis was still in the London banking world when he started writing articles satirizing it. His first piece for The New Republic ("It was basically just making fun of British bankers," Lewis said) was a PR nightmare for his firm Salomon Brothers. But it didn't stop him: Lewis continued writing articles using his mother's name, Diana Bleeker, as a pseudonym. Soon enough, "Diana Bleeker" got a contract with Business Magazine -- meaning Lewis could leave his job to pursue his passion. "It became clear I could make a living -- if not as fancy a living -- as a writer," <a href="http://www.publishersweekly.com/pw/print/19991018/32870-michael-lewis-seeking-the-soul-of-silicon-valley.html" target="_blank">Lewis told Publishers Weekly</a>, "and so I quit."




  • Amy Tan


    Before Amy Tan was a bestselling author, she ran a technical-writing business with a partner, focusing largely on account management. Feeling stifled and unfulfilled in her position, Tan shared with her partner that she wanted to do more writing, <a href="http://www.rd.com/advice/work-career/how-famous-people-achieved-their-dreams/" target="_blank">Reader's Digest reported</a>. But he told her to keep doing what she was "most good at" -- chasing down contractors and collecting bills, her least favorite part of the job -- and that writing was her weakest skill. She fought back repeatedly, and when her partner refused to acknowledge her skill, Tan ultimately quit. She took on a heavy load of freelance assignments, and went on to write a handful of best-selling novels.




  • Debbie Wasserman Schultz


    As a recent college graduate, aspiring politician Debbie Wasserman Schultz helped Florida congressman Peter Deutsch successfully run for the U.S. House of Representatives -- and then got his blessing to go after his seat in the Florida House of Representatives. Wasserman Schultz went from neighborhood to neighborhood, personally knocking on the doors of more than 25,000 people in her home state of Florida to win the seat. She became the youngest female legislator in the state's history at just 26 years old, <a href="http://www.businessinsider.com/what-successful-people-did-in-their-20s-2013-3?op=1#ixzz2c3H9zRay" target="_blank">Business Insider reports</a>.




  • Chris Putnam


    Facebook founder and CEO Mark Zuckerberg lives by the maxim "Fortune favors the bold" -- and perhaps none of his employees at Facebook personify that idea more than Chris Putnam. In 2005, the young tech whiz <a href="http://www.businessinsider.com/how-i-attacked-facebook-with-a-virus-and-got-a-job--at-facebook-2011-2" target="_blank">hacked the site </a>and wrote a computer virus to make user profiles look like MySpace pages. The hack lasted less than a day, but it caught the attention of COO Dustin Moskovitz, with whom Putnam developed a relationship via Facebook message and AIM. Soon afterwards, Putnam received an offer from Facebook, dropped out of college in Georgia, and moved to Silicon Valley to join the team. With Facebook's founding ethos of risk-taking, it's not surprising that the company decided to hire Putnam. As Zuckerberg <a href="http://www.cbsnews.com/8301-505125_162-28248860/facebooks-mark-zuckerberg-insights-for-entrepreneurs/" target="_blank">once said</a>, "The biggest risk is not taking any risk. In a world that changing really quickly, the only strategy that is guaranteed to fail is not taking risks."
