John Carter was shot in the head, left in a coma for 99 days and told he’d never walk again.
Yet on Wednesday night he stood tall – steady, smiling and surrounded by people who came to support him.
“I had a choice – go back to the life I knew, or take the left and go to a halfway house,” said John Carter, author of “Triggered to Change: A Life Full of Turbulence” and owner of Titanium Health and Fitness in Brookline. “That left turn saved my life.”
In a cozy corner of Hummingbird Books in Newton, Carter welcomed both familiar faces and newcomers for a free event Wednesday marking the release of his autobiography.
The evening began with remarks from moderator Matthew Gregory, a client at Carter’s gym. It was followed by a conversation between Gregory and Carter, a question-and-answer session with audience members, and a book signing.
In his autobiography, Carter, 57, recounts his early years surrounded by organized crime and addiction. He tried to follow in the footsteps of his father – a member of the mob – and quickly fell into dealing drugs, drinking and gambling.
“My life spiraled out of control,” Carter said.
He was shot in the back of the head, which he referred to as “the violent moment in 1992.” After surviving the injury, he found himself in a wheelchair, weighing 350 pounds, and still abusing and dealing substances. When police raided his home – 12 officers with guns drawn – Carter’s first thought was, “Thank God it’s over.” Authorities found drugs and cash. Carter spent 10 years in prison.
But “Triggered to Change” isn’t about trauma – it’s about what comes after. The book focuses on resilience, recovery and choosing accountability over victimhood.
“You don’t give up,” Carter said. “You get up. You keep going. Even if it’s slow, forward is forward.”

After the Q&A, Carter’s son, Matthew Michael Carter, 20, reflected on the lessons his father passed down. In an interview, he said the most important was not to quit, even when giving up felt easier.
“There were so many times I wanted to give up – especially during COVID,” Matthew said. “I was failing school and just wanted to drop out, but he wouldn’t let me.”
Carter pushed him to finish high school and encouraged him to complete a year at Plymouth State University before making any decisions.
“It’s OK to quit,” Matthew said, “but make sure you actually experience it all before you quit – because you might not know if you liked it or not.”
Though he hasn’t finished reading “Triggered to Change,” Matthew said what he has read offered a deeper understanding.
“I didn’t realize how deep it all went — how planned the shooting was, or that someone else was even in the house,” he said. “It’s crazy to think that if one thing had gone differently, I wouldn’t be here.”
Shelley McHale, who served as Hummingbird Books’ original manager when it opened in 2022 and was present during Wednesday’s event, said Carter’s story clearly resonated with the audience.
“We try to host meaningful events for local authors,” McHale said. “There was strong energy in the room. Everyone seemed genuinely invested in what John had to say.”
McHale added that the store hosts around 50 events a year, balancing larger names with emerging local voices. “For authors just starting out, it’s tough to break in,” she said. “But when there’s a compelling story, we want to make space for it.”

Ian Rossin, Carter’s publicist, helped promote the event and saw the turnout as a promising sign for Carter’s message.
“This was John’s first public speaking event since his TED Talk in 2019,” Rossin said. “He’s done podcasts recently but nothing like this. It really meant something to see that crowd.”
Rossin believes the book’s potential impact extends across audiences. “It’s a story about resilience, sure, but it’s also about fatherhood, addiction and second chances,” he said. “No matter who you are, there’s something in there that will stick with you.”
Employees from the Service Dog Project, a Massachusetts-based nonprofit that breeds and trains Great Danes for people with mobility impairments, also attended. Carter has had two service dogs from the organization: Jagger, who retired because of health issues, and Turbulence, who now accompanies him daily.
Karen Mallory, an employee with the group, has followed Carter’s story for years. “He’s remarkable,” she said. “To see the disadvantages and challenges he’s faced— some of them self-inflicted— and where he is now? It’s a testament to the human spirit.”
Jami Snow, another employee, added that Carter’s attitude mirrors the mission of their organization. “He never gives up. He just keeps going,” she said. “A lot of people could benefit from that.”
Carter announced that a portion of the book’s proceeds will go toward supporting the Service Dog Project’s operations.
For Carter, the goal wasn’t just to tell his story, but to show others change is possible. “You just have to make the choice,” he said. “Then do the work.”
