It used to be amusing to me, but now I am boarder-line frantic. Watching good (sometimes VERY good) people go past the point of amazing and into the realm of destructive--to themselves.
In my humble opinion, the recent market melt-down was entirely a function, and classic example, of this.
Be confident Yes, have a self-assured posture, Yes. But don't cross over into "I can do no wrong," or "I know better than everyone" That is a slippery slope to both yourself and those who would follow you,.
Recently, I had occasion witness just this. This person and his team were good, perhaps even VERY good, they had even established and published "rules" for how they operate. They had build an expectation and created much confidence and progress as a function of such. People knew what they could count on. The "rule of law" lead to great productivity.
But then... along came a circumstance that would under normal circumstances easily fit into the rule-set, but they chose to ignore that and go a separate way. Loss ensued. Maybe not economic loss at first, but loss of respect (even self respect), loss of confidence in them and loss of ability to "posture up." I am certain economic loss will follow. Such a shame, such a loss, such a waste.
Anyway, life is good, we should be good and do good--even when it is hard or unpopular (and this one wasn't even that)--that is the mark of a fine individual and certain leader. That is who I would choose to be and follow.
So, yes, do your press releases, do them as you normally would. But please, please, please don't believe them--no-one else does!
