Advising the Key Club is probably one of the most fulfilling experiences you can have as a teacher. Your students' capacity to love and do good deeds will never cease to surprise and amaze you. I worked at an inner city school where students didn't exactly have extra money to donate for charitable causes. If anything, many of them were the charitable cause. It didn't stop them from giving their time and resources to the charities we supported. If you ever have a shred of doubt about the millennial generation, advise the Key Club and let them change your mind.
