Whether making life-changing choices or considering seemingly small day-to-day decisions, to choose oftentimes means to take a step into the unknown. In The Decision That Changed My Life, author Ganel-Lyn Condie explores some of the life-altering choices made by sixteen notable and everyday Latter-day Saints and the chain of events that followed those decisions that affected other people's lives. From the broad impact of Janice Kapp Perry's course-changing decision to pursue music to the significance of Chris Carter's converting to the gospel as a young boy, each story demonstrates the potential ripple effects of our decisions. While following the promptings of the Spirit without a full understanding of the outcome requires great faith, sometimes making that one decision has the power to change our lives—and the world.
