Former First Lady Michelle Obama lights the path ahead for our 2020 graduates with a warm and hopeful message. Guided by wisdom garnered from her own life, she offers four of her biggest lessons: (1) Life will always be uncertain. (2) Treating people right never fails you. (3) Share your voice with the world. (4) Anger is a powerful, useful force but, when left alone and unchecked, it corrodes and destroys us. When it is focused and channeled into something more, "that," Michelle Obama says, "is the stuff that changes history."
