The ultimate guide on leadership from the co-author of Extreme Ownership. In the military, a field manual provides instructions in simple, clear, step-by-step language to help soldiers complete their mission. In the civilian sector, books offer information on everything from fixing a leaky faucet to developing an effective workout program to cooking a good steak. But what if you are promoted into a new position leading your former peers? What if you don't get selected for the leadership position you wanted? How do you overcome imposter syndrome, when you aren't sure you should be leading? As a leader, how do you judiciously dole out punishment? What about reward? How do you build trust with your both your superiors and your subordinates? How do you deliver truthful criticism up and down the chain of command in a tactful and positive way? These are all questions about leadership-the most complex of all human endeavors.
