Arthur C. Brooks offers a hopeful, research-driven guide to thriving emotionally and spiritually as we age, by embracing new strengths and redefining success.

In From Strength to Strength: Finding Success, Happiness, and Deep Purpose in the Second Half of Life, Brooks explores the psychological and neurological shifts that occur as we grow older—and how clinging to past achievements can lead to dissatisfaction. Drawing on science, philosophy, and faith, he encourages readers to pivot from fluid intelligence (problem-solving and innovation) to crystallized intelligence (wisdom and teaching), which naturally strengthens with age. Through personal stories and practical advice, Brooks shows how letting go of ego, deepening relationships, and serving others can lead to lasting fulfillment. It’s a compassionate roadmap for turning life’s second act into its most meaningful chapter.
