A teacher named Ashley looked around the classroom, enjoying a blessed moment of quiet after the students left at the end of the day. “Ashley, the teacher, that’s me,” she said proudly to the empty room. “But why am I doing this?” she asked herself quietly—and realized she wasn’t always sure of the answer. But then she remembered one reason: she was teaching for Nadia, who sat at the table to the left, always smiled so well and always (well, usually) tried hard. And another reason: she was teaching for Lincoln, tired old Lincoln, who needed her help more than he realized. She remembered twenty other reasons—twenty other students. And one last reason: she was also teaching for herself, challenging herself to see if she really could keep up with twenty-two young people at once, and really accomplish something worthwhile with them. She was teaching so she could keep growing as a person, keep connecting with others, keep learning new ideas. That’s why she was teaching.
