Smile a lot, and when it hits the fan and all else is lost, smile some more. Nobody walks away from a good or bad message more empowered when the meeting ends with a smile. Even when it's the final turn to the door. Al Gore didn't smile as much as GW, and Clinton smiled more than GW's dad. It was the right thing to do because the winds of change had eroded many avenues to the other 49 rules of leadership in that culture, and I couldn't live like that or with that.
Leaders radiate full chain purpose.
Good leaders, no, excellent leaders, have the ability to instill this understanding and focus. Real leaders know when it's time to follow. Real leaders don't get insecure about doing this. A good leader instills empowerment, encourages innovations, allows mistakes to happen. Leaders encourage a fun environment.
