Which detail from "President Obama's Third Annual Back to School Speech" best supports the idea that teachers can have a meaningful effect on their students' lives. "They don't --they sure don't do it for the big salary. They do it for you. They do it because nothing gives them more satisfaction than seeing you learn. " "And they say, I had something to do with that, that wonderful young person who is going to succeed." "They live for those moments when something clicks; when you amaze them with your intellect or your vocabulary, or they see what kind of person you're becoming." "Teachers are the men and women who might be working harder than just about anybody these days."
