Effective leaders lead successful teams that accomplish their mission and win. Ineffective leaders do not.

hey must literally risk life and limb to accomplish the mission. For this reason, they must believe in the cause for which they are fighting. They must believe in the plan they are asked to execute, and most important, they must believe in and trust the leader they are asked to follow. This is especially true in the SEAL Teams, where innovation and input from everyone (including the most junior personnel) are encouraged.

Not knowing the why prohibits you from believing in the mission. When you are in a leadership position, that is a recipe for failure, and it is unacceptable
