Book excerpt: Brett Carter is a hotshot on his basketball team, the Wildcats—or at least he was. After missing an easy layup shot at the buzzer in an important game, he feels like a total loser. But things get worse. At his best friend’s birthday party at a rock climbing center, Brett freezes on the wall. Then he blows an easy question in the American history bee at school. He is losing his confidence fast, both on and off the court—and the championship game is coming up. Can Brett overcome his fears and play like a “winner” again?
