What happens when the world is too loud, too bright, and too fast-and your mind sees patterns no one else notices?Born at just one pound, Mathieu Vaillancourt was never supposed to speak clearly, or pass first grade. Doctors underestimated him. Schools misunderstood him. The world tried-again and again-to force him to fit a mold not designed for his brain.This is the deeply personal, unfiltered story of growing up autistic before autism was widely understood.In Finding Patterns, Vaillancourt traces his life through the patterns that shaped it: premature birth, misdiagnosis, bullying, autistic burnout, sensory overload, and relentless resilience. Diagnosed as a teenager after a devastating mental health crisis, he slowly learns to understand his mind-not as broken, but as differently wired.This is not a medical manual.This is not a miracle-cure story.And this is not inspiration porn.It is the honest account of an autistic life lived from the inside.With sharp insight, dark humor, and quiet defiance, Vaillancourt writes about masking, burnout, passion, travel, introversion, and the daily negotiation between survival and dignity in a neurotypical world. The book's second section offers practical, lived-experience reflections for parents, caregivers, and anyone seeking to better understand autism-without fear or condescension.This book is for: Autistic adults who rarely see themselves reflected honestlyParents searching for understanding rather than false hopeEducators, clinicians, and allies who want to listen, not lectureAnyone who has ever been underestimated-and kept going anywayThe moral is simple: never give up.Even in the narrowest tunnel, there is still light.
