Danica: Then when I spoke in front of congress and studied this report, I became crystal clear that middle school is the time when most young girls start to lose confidence in math, not their grades. They're doing just fine, but they lose some confidence. That's the beginning of the end because when you lose your confidence, you're telling yourself a story. We all tell ourselves stories, the story of our own life. We repeat it many, many times. Then we find evidence to fulfill that story, whatever it is. That's how people get stuck. This is one of those things that people get stuck in, whether it's because they are afraid of not being popular because they think that if they're smart then they’ll be intimidating to their friends, they’ll lose their friends, or if they see all of the archetypes of the nerdy math student, "I don't want to be nerdy." When you're in middle school, that's the time when math gets more complicated and also when your hormones are just rushing around. You're confused. You're trying to figure out who you are.
