What if, over the course of 50 hours, you could tap into a limitless source of power you never knew existed? In School of Grit, certified and licensed Unbeatable Mind coach Brad Ritter invites readers on an unforgettable journey through 50 hours of SEALFIT's infamous Kokoro Camp - the world's most grueling physical, mental, and emotional challenge for civilians. Without sleep and with minimal food and water, Ritter pushed himself to the outermost brink of survival on his way toward a remarkable transformation of his mind, body, and soul. He masterfully draws parallels between the profound lessons he learned and real-world, everyday experiences, challenging readers every step of the way to dig deeper, work harder, and go further than they ever have before. School of Grit will show you how to master your inner dialogue, raise your self-imposed ceiling, and condition your mindset to seek purposeful pain and adversity. Without challenge, there isn't change. To achieve your fullest potential, you have to stop taking the path of least resistance. There is no shortcut. Commit to a lifestyle of discipline and do the daily work. Grow your grit from the inside out and from the outside in every day. What are you waiting for?
