In that debuted on Christmas Eve, Oprah Winfrey – who had bought a 10 percent stake in the company in October 2015 – speaks feelingly about her past weight losses and gains, and invites her listeners to give Weight Watchers a try. Or, to quote the title of the ad, to join her on a "new Weight Watchers journey," a trip with a vaguely defined destination and a sentimental soundtrack.

Oprah fans may recognize the central metaphor of this message from dozens of "weight-loss journeys" – her own and others' – featured on Oprah's long-running (1986 to 2011) television show. Or maybe they'll have encountered it somewhere else: when I searched for "weight-loss journey" I found more than 26 million matches.

And that's only the beginning of the journey journey. Over the last 35 or so years, journey has become one of our culture's dominant metaphors, a handy stand-in for experience, ordeal, process, test, investigation, story, and series of events.

Software developers speak of the : a series of steps that represent the way a person might interact with the thing being designed. A weight-loss app called Rise congratulates users on "completing another week of your diet journey." The package containing National Geographic's ancestry test compares DNA research to a journey.

After losing the Iowa caucuses to Cruz, Donald Trump told his supporters that the campaign had been . A 2013 biography of former secretary of state and current Democratic presidential candidate Hillary Clinton is  The Secretary: A Journey with Hillary Clinton from Beirut to the Heart of American Power. 2020欧洲杯时间And headline writers have found it hard to resist the rhyming charm of when writing about Clinton's opponent, Bernie Sanders, a U.S. senator from Vermont.

None of these usages hews to the original and literal sense of journey: a defined course of travel over land (as opposed to voyage, which takes place on water). When journey entered English from Old French journee, in the 13th century, it meant both a single day and a single day's travel: jour is French for day. By the 1400s it could be qualified: a three-day journey, the Sun's daily journey. (A synonym, trip, also comes to us from French; it originally meant only "a light movement of the feet"; not until the late 1600s did it signify "a short voyage or journey.")

The metaphorical sense of journey – what the OED defines as "the 'pilgrimage' or passage through life" – is also very old. The dictionary's earliest citation for this sense of journey is from around 1225, in a guidebook for nuns: "The pilgrim in the world's way ... many things may hinder him on his journey." English translations of the Bible use journey almost exclusively literally, to mean travel, but in his Sonnet 27, published in 1609, Shakespeare writes of a (figurative) "journey in my head." In the late 19th century, English translators rendered the words of the classical Chinese philosopher Lao-tzu (6th century BCE) as "The journey of a thousand miles must begin with a single step" – advice clearly meant to be interpreted symbolically.

For many years the metaphor was used sparingly: My 1980 edition of Bartlett's Familiar Quotations contains only a couple dozen journey citations (including, from 1956, Eugene O'Neill's Long Day's Journey into Night). As it happens, 1980 represents a turning point in journey's journey: the year the metaphor began pervading popular discourse.

Nineteen-eighty was the year George Lakoff, a linguist, and Mark Johnson, a philosopher, published , which explained how figurative language reflects and shapes our thinking. Journey figured prominently in the book: Our words reveal that we think of love as a journey ("we're at a crossroads," "the relationship isn't going anywhere") and that, like our medieval ancestors, we also think of life as a journey ("a good start in life," "he'll go places"). Metaphors We Live By was and remains hugely influential in academic circles and beyond.

The advent of New Age philosophy around this time, with its Eastern influences and its focus on mind-body harmony, also encouraged journey-ing. The earliest citation I found for "the cancer journey" is in a 1979 issue of the literary magazine ; today, a search for "cancer journey" turns up tens of thousands of matches. "The Breast Cancer Journey" is a primary section of the Susan G. Komen . Under the influence in part of The Healing Journey, a 1983 book by Claudio Naranjo – a Chilean-born psychiatrist who has written widely about spiritual practices – journey became attached to non-cancer afflictions as well. See, for example, Beautiful Boy: A Father's Journey Through His Son's Addiction (2009); The Journey from Abandonment to Healing (2014); and The Journey of the Heroic Parent (2016).

Then there are the corporate journey-ers who like to portray their dealings as a grand adventure. One of the first to do so was Apple founder Steve Jobs, who was fond of saying (but almost certainly did not coin) "The journey is the reward." The phrase was even used as the title of . Today Silicon Valley is abuzz with journeys, most often invoked when a business goes bust. Last December, for example, when the ride-hailing app Sidecar, based in San Francisco, ceased operations, co-founder Sunil Paul the world: "This is the end of the road for the Sidecar ride and delivery service, but it's by no means the end of the journey for the company."

Rochelle Kopp, a consultant to Bay Area and Japanese companies who is writing , told me that this usage of journey "pairs well with the Silicon Valley penchant to glorify failure as a way to grow" and suggests "that even though things have not gone well, it's just a setback on the longer journey, which will ultimately lead to your desired goal."

(Kopp, who is fluent in Japanese, also noted she's unable to translate this metaphorical journey. To use a Japanese word for trip or travel 2020欧洲杯时间in a figurative sense, she said, "would be completely nonsensical.")

Finally, there's the pop-culture journey embraced by media stars like Oprah and those who aspire to stardom. The English rock band The Who were pioneers, performing the song "Amazing Journey" in their 1969 rock opera Tommy (the journey of the title is a psychedelic one); Amazing Journey is also the title of a 2007 documentary about the band. "It's been an incredible journey" is often the parting summary of rejected contestants on "reality" shows like The Bachelor, which first aired in 2002 and is still going strong. "Once rare and remarkable," Stacey Woods, who writes about language for Esquire, "incredible journeys have become incredibly commonplace. Most people are either on one, have just completed one, or are between them."

Most incredibly of all, as recently as a few decades ago we managed to live, love, and compete without calling those activities journeys. To borrow a phrase from those veteran voyagers the Grateful Dead: what a long, strange trip it's been.
