As a practitioner of science-based, data-driven continuous improvement processes, first in business and then applied more broadly to other areas of my life, I've been aware of the benefits of scientific, rational decision making. Until reading this book, however, I had no concept of how this approach could be applied to some of the most high level questions of human existence. I would encourage anyone wishing to improve their mental and physical well being to give this short but impactful book a read, particularly if you've never given a lot of intentional thought to your meaning and purpose in life. Dr. Gleb Tsipursky does a terrific job of summarizing and citing recent research in psychology, cognitive neuroscience, and other disciplines to put one on a path to discovering meaning and purpose through science. As someone who has not had much exposure to these deep, philosophical questions, other than perhaps from watching Monty Python's Meaning of Life, this book offers a great start. The book summarizes several common philosophical perspectives on finding meaning and purpose, including Christianity, Eastern-based philosophy, existentialism, and humanism. There are many paths to finding one's meaning and purpose. Dr. Tsipursky shows scientific evidence that a strong sense of meaning and purpose will improve your life, and that science can help you find it.
