Trent Preszler had an estranged relationship with his father, who died of cancer in 2014. His only inheritance was his father's toolbox. Setting out to build a canoe from scratch using his father's tools, Preszler saw his project lead to life-changing realizations about self-discovery, reconciliation and forgiveness. "CBS This Morning" lead national correspondent David Begnaud talks with Preszler about the hidden meanings of building these one-of-a-kind canoes, and about Preszler's memoir, "Little and Often."
