Consistent motivation usually comes from a consuming desire to be able to perform at your best under pressure, namely, the pressure produced by tough competition. If a player needed me to light a fire under him by turning the other team into a demon, he was lacking something I couldn't give him.
Bill WalshThere is another side [to ego] that can wreck a team or an organization. That is being distracted by your own importance. It can come from your insecurity in working with others. It can be the need to draw attention to yourself in the public arena. It can be a feeling that others are a threat to your own territory. These are all negative manifestations of ego, and if you are not alert to them, you get diverted and your work becomes diffused. Ego in these cases makes people insensitive to how they work with others and it ends up interfering with the real goal of any group efforts.
