J.J. Watt advises young athletes to find a rival -- someone who scares them -- whether they're far away or just across town. Sometimes they might even be family. The Texans defensive end says that person should be dedicated to taking you and defeating you. Your competitor will drive you to stay late, come in early and become obsessed. Gatorade showcases moments from storied rivalries like the Chicago Bears vs. the Green Bay Packers and Magic Johnson vs. Larry Bird while insisting that, eventually, the rivalries will foster respect, admiration and raise your game.
