What Happened Yesterday
Couldn't load pickup availability
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.

This book was so amazing. I wanted to take it slow but I genuinely could not put it down. I personally think this book should be read by all preteens and teenagers who are struggling with things like anxiety or have issues with school and social dynamics. I loved being able to relate to someone in private and reflect after each chapter and also see steps that might be helpful to me in the future as i struggle with some of these same topics talked about in this book. SO well written and Matt did an amazing job of being transparent and open with what he went through and the events in his life that shaped him and it was an amazing read. Thank you so much! This book was so beautiful and inspiring:) 100% worth every penny and moment spent reading!
Highly recommend for Sturniolo fans. Bought this book for my daughter who absolutely loves the triplets and was over the moon when the book arrived.It's not a long, complicated book, easy to read and has a great positive message. I'm thrilled that she's actually reading it.In the book, Matt talks about his own mental health and the support of his family as he overcame his struggles.I highly recommend.
I have always been a fan of Matt from the start. I’ve always related to him being more introverted, shy, and anxious. I love that he opened up in this book and shared his struggles. Read the book in one sitting, I could not put it down! Will probably reread it several times.
It's such an amazing book with what I've read so far even if someone isn't a Sturniolo fan they should still read this book I relate to Matt so much and I could never talk about my live or how I struggle with things like he does thank you Matt for your amazing autobiography
This book made me cry. Twice. As someone who has dealt with anxiety and depression since the age of 4, I was able to relate to this book on so many levels. As an “older” fan, I came across the Sturniolo Triplets during a rough patch and they made me laugh. But this book allowed me to understand Matt on a deeper level and all I want to do is hug him and tell him thank you. My hope is that he continues to advocate for mental health and I hope others read this book and realize that they’re not alone. Thank You Matt for writing this book!
