David Mezzapelle’s book Contagious Optimism is a new book on his old and well established philosophy and practical way of life. He can’t help it. It has been a life-long way of functioning for him. He was the child who loved falling off his bicycle. To listen to him talk about the upside of the downside is instructive, delightful and a whale of a good time. His generosity is that he is passing on the joy of it to others. He gives tips about how to achieve it, and he gives permission to let yourself surrender to the optimism that will be good for you in so many ways.
