I think what's happening here is, there's a group or maybe one person who is saying this is gonna be the definition and this is what we want to get the kids to do now.
“I want to find that defining moment that you're satisfied and you've done what you want to do in your life.”
“But if I were to sum up who Barack Obama is and how he plans to meet this moment with one word, that word would be 'responsibility.' Responsibility to each other, our families, our communities, our country, and our world.”
