Jocko is basically correct in this video, but he does not address the most important prerequisite. . . CONFIDENCE.
To tackle life’s ‘bad-breaks’ and to then overcome them, you need confidence. Confidence only comes by tackling smaller problems and succeeding again and again. Strength and courage will get you individual achievements, which when repeated many times over, brings confidence to your personality. Then you can tackle any problem that gets thrown your way, knowing that you can solve it.
