Ego over Mission.

A strong, healthy ego is a real source of a leader's strength and confidence. The danger is the unhealthy ego that quietly bends the analysis toward self-interest - because the decision is meant to serve the mission, not the decision-maker.

When the 'I' is subordinated to the 'we,' the architecture of the decision holds and the choices get better. It is never about you; it is about the mission. That is the discipline that endures.
