Best known as one-third of the Sturniolo Triplets, YouTuber and social media personality 

Matt Sturniolo unpacks his complex past and makes his literary debut with What 

Happened Yesterday.

From simple yet meaningful milestones such as learning to drive, confusing moments in 

therapy, and navigating overnight virality, to the significant loss of his childhood home 

due to a house fire and the passing of his grandfather, Matt shares with dark humor, raw 

honesty, and his signature wit what no video could ever capture.

But this is not a sob story. It's a reminder that progress isn't always some huge life-

changing moment. Sometimes, it's as small as standing in a grocery store line alone, or 

making it through an entire school day without running for the door.

As Matt's mom always told him: Yesterday's problems shouldn't affect today. Because 

what once felt like mistakes or painful experiences . . . is simply what happened 

yesterday.
