If you haven’t heard of endurance runner and former Navy SEAL David Goggins, then picking up his latest book Never Finished will blow your mind.
It should actually be titled 'How To Be A Savage 101’.
(2018) was his debut memoir and an introduction to the power of the mind. (2022) is a journey into Goggins’ Mental Lab, where he developed the philosophy, psychology and strategies which enabled him to learn that what he thought was his limit was only his beginning.
