Richard Paul Evans is a prolific writer, having published dozens of books, including nonfiction works on money management and his bestselling fictional “Christmas Box” series. These words come from the series’ last installment, “The Letter,” in which a father grieves for his young daughter and finds a letter from his own estranged mother. Evans’ story focuses on the choices we make, and all the feelings, both good and bad, that ripple after them. His words here remind us that the experiences of our lives, from the difficult to the joyful, define us as much as we define them. In the end, our actions and the way we treated others will be our legacy.
