The glorious part should be obvious by now: it's in the ability to change people's minds with a hard-hitting piece of journalism, or to educate the masses using just a few thousand words or a dozen photos.
There have been a handful of photo journalists who've changed what people think about events, wars, and places. Journeyman photographer Eddie Adams captured one of the most iconic images in history—"The Saigon Execution."
Adams's photo of the public killing of a Vietcong prisoner on the street during the Tet Offensive did more than just win him the 1969 Pulitzer Prize for Spot News Reporting. It transformed the American view of the Vietnam War. It shed light on the atrocities committed on both sides.
Journalists might say they're in it for the nobler reasons—uncovering the truth, telling it to the world, and all that stuff. And surely those motives are there. But it still feels pretty glorious to be the person who breaks the big story. You can literally change the course of history.
Or, if that super-serious-style glory isn't what you're looking for, you could instead tell the masses about the unfortunate dress Miley Cyrus was wearing at the VMAs the other night. That works too.
