Great Groups need to know that the person at the top will fight like a tiger for them.

Keep reminding people of what's important and that their fates are correlated.

The crucible is a dividing line, a turning point, and those who have gone through it feel they are very different from the way they were before. Believing that they have been transformed or have transformed themselves, those who survive the crucible (and many don't) are more confident, more willing to take future risks. That new self-confidence is grounded in the belief that he or she has done something hard and done it well.

Great leaders love talent and know where to find it. They surround themselves with talented people who can work effectively together.

Too many companies believe people are interchangeable. Truly gifted people never are. They have unique talents. Such people cannot be forced into roles they are not suited for, nor should they be. Effective leaders allow great people to do the work they were born to do.

In the face of ambiguity, uncertainty, and conflicting demands, often under great time pressure, leaders must make decisions and take effective actions to assure the survival and success of their organizations. This is how leaders add value to their organizations. They lead them to success by exercising good judgment, by making smart calls when especially difficult and complicated decisions simply must be made, and then ensuring that they are well executed.

Leadership is a function of knowing yourself, having a vision that is well communicated, building trust among colleagues, and taking effective action to realize your own leadership potential.
