tunnel vision

So we have to let our lights shine on top of a hill but it can't be visible (to us). I guess it's just a natural thing to do as a human to concentrate and focus on ourselves. It's also hard when you put yourself in a leadership role because a lot of people are looking at you to act a certain way. Like if a military leader shows weakness or doubt then his troops might falter. So as a leader you might be too preoccupied on how your troops are perceiving you. But the best military leaders in history probably didnt become bogged down in how they look but were focused on the objective to be accomplished. Must've took good discipline.
