The first thing I think about is leadership. I think a good leader should share the victory with everyone, and be as generous and inclusive as possible in the celebration.
At the same time, I think a good leader should take responsibility for a defeat upon himself while shielding his or her team from as much blame as possible.
Although this kind of leadership seems rare these days, I think it's the best model to attract, retain, and inspire staff :)
