"Promise me Dad" is a touching book and one of the best books I have ever had. It is so disheartening to read about how Beau Biden was suffering, but what I marveled at was how Joe Biden held on to his purpose, despite facing a tragedy. The part where Hunter is always in readiness to help his brother was, very comforting. But the support that Barack Obama showed to Joe Biden especially offering to lend him money was one of the things that made me marvel at his goodness. Reading this book what I have learned from Joe and Beau Biden is that: Always hold onto your purpose in life, no matter how many hardships you face, and always be calm in the face of adversity. I swear that this book has changed my whole perspective on life.
