27 Questions To Make You Sweat is refreshingly honest. The book has made me evaluate my own life and I was comforted by being guided by Gregg's thought provoking questions. Some of the questions were existential in nature ("How Do You Know What You Know?"), while others made me think critically about my own actions ("How Often Are You Motivated By Guilt?"). Overall, Gregg Sulzer's book is a great read for anyone that wants to find more meaning to their life, think about their actions in a more critical way, and improve themselves as a human being. Thank you Gregg for writing such an inspiring book that has led to some deep discussions with my close friends, family, and even strangers!
