"If I'm not home accepting what I can't…

The Serenity Prayer is: “God, grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference.”

“If I’m not home accepting what I can’t change, I’m probably out changing what I can’t accept” was posted in newspapers on October 18, 1978, in the “Pot-Shots” syndicated feature by cartoonist Ashleigh Brilliant.

“I’m no longer accepting the things I cannot change. I’m changing the things I cannot accept” is a saying that has been printed on many images. “Is No Longer Accepting the things I can not Change! I Am Changing the Things I can not Accept!” was posted on Twitter by John Tafaro on May 31, 2010. “I am no longer accepting the things I cannot change! I am changing the things I cannot accept!” was posted on Twitter by Amanda Blake on November 1, 2010. “I’m no longer accepting the things I cannot change. I’m changing the things I cannot accept. #LiveFreeorDie” was posted on Twitter by William Munny on August 14, 2012.

This version of the saying probably originated on an image. This image (featuring a Native American) by Idle No More possibly dates to November 2012.

How an Angela Davis Quote Wound Up at the Barclays Center Subway Entrance
Credit an anonymous partner of the arena operator, which—surprise—controls that commercial space.

Sometime within the next twelve days, that plaza entrance offered a non-marketing message in stark black-and-white: “I am no longer accepting the things I cannot change. I am changing the things I can no longer accept,” attributed to “Angela Davis, American Political Activist, Educator, and Author.”

The banner has no corporate or institutional credit, just the hashtag #BLACKLIVESMATTER. It’s gotten little notice on social media–here’s one Twitter salute from June 19, keyed to #Juneteenth, though it is unclear when the banner went up.

Who’s ‘anonymous partner’ behind Angela Davis quote at Barclays subway entrance?
By Net Income Jul 9, 2020, 7:35pm EDT
Sometime between June 7, when Barclays Center replaced advertising inside the oculus with a Martin Luther King quote, and June 19, Juneteenth, another ad went down above the arena subway entrance opposite the oculus. This time, the message displayed on a large banner was a quote from Angela Davis, the California-based and often controversial political activist and writer.

As Norman Oder reports in The Bklyner, the quote reads, in black-and-white lettering, “I am no longer accepting the things I cannot change. I am changing the things I can no longer accept,”

Is the quote posted at the Barclays Center transit entrance really from Angela Davis? (It’s common, but not sourced.)

I had seen the quote on this University of California Berkeley page, 400 Years of Resistance to Slavery and Injustice, excerpted at right, and thus didn’t have suspicions.

However, as shown in the screenshot at left, the gift shop of New York Public Library’s Schomburg Center for Research in Black Culture—“one of the world’s leading cultural institutions devoted to the research, preservation, and exhibition of materials focused on African American, African Diaspora, and African experiences”—offers an Angela Davis magnet with that quote.
