Stumbling back to his corner after barely surviving a round's worth of punishment and submission attempts from a hard-hitting opponent, Dave "Meanberg" Greenberg hears his MMA coach bellow unexpected words: "Sit down! Shut up! You're gonna win this thing!"These words echo far beyond Dave's first amateur cage fight to become a recurring theme in his challenging life. Little did he know then, but this would just be the start of fighting for his life and coming out on top. He learns that his determination and grit can overpower not only opponents in the cage, but also life-threatening car accidents, injuries that compromise his dream of fighting again, and losses that penetrate deeper than his physical wounds. What starts out as a glimpse into the life of an MMA fighter transforms into a journey of growing up and finding oneself by confronting adversity. Dave's story reminds us that we are far more capable than we give ourselves credit for.
