In this inspiring series of letters to his grandchildren, David Suzuki offers grandfatherly advice mixed with stories from his own remarkable life and explores what makes life meaningful. He challenges his grandchildren - and us - to do everything at full tilt. He explains why sports, fishing, feminism, and failure are important; why it is dangerous to deny our biological nature; and why First Nations must lead a revolution. Drawing on his own experiences and the wisdom he has gained over his long life, he decries the lack of elders and grandparents in the lives of many people, especially immigrants, and champions the importance of heroes. And he even has something to say about fashion. The book also provides an intimate look at Suzuki's life as a father and grandfather with letters that are chock-full of anecdotes about his children and grandchildren when they were small. As he ponders life's deepest questions and offers up a lifetime of wisdom, Suzuki inspires us all to live with courage, conviction, and passion.
