Listen up, students. We interrupt this classroom for a lesson from President Barack Obama. In a speech to be broadcast in schools nationwide on Tuesday, Obama urges American kids to set goals, take on personal responsibility, and stay clean. "I hope you'll all wash your hands a lot, and stay home from school when you don't feel well," he says. The president also tries to reset priorities: "You get the sense from TV that you can be rich and successful without any hard work—that your ticket to success is through rapping or basketball or being a reality-TV star, when chances are, you're not going to be any of those things." He explains, "Being successful is hard. You won't love every subject you study. You won't click with every teacher."
