Retired Navy SEAL Andy Stumpf discusses his new book 'Drownproof: Eight Life Lessons to Keep Your Head Above Water,' revealing why SEALs drown despite water training, the critical importance of fundamentals in jiu-jitsu and life, and how exceptional people surround themselves with other exceptional people—not dipshits. Most exceptional people achieve success through the influence of their mentors and peers, not alone; isolated excellence without a strong support network is nearly impossible. Navy SEALs die by drowning in real operations despite extensive water training because training must be dangerous enough to prepare soldiers for actual combat conditions; lowering standards costs more lives than maintaining rigorous protocols.
