 One of the demands of leadership in producing change that I think is difficult is you've got to be both strategic and tactical. President Kennedy, when he said we're going to put people on the moon and bring them back safely within a decade, certainly a strategic issue, but he, through the people who worked for him, made sure that the tactical follow-up was there and that both weren't left off or edges left off the spacecraft and the likes. I think unfortunately you've got to pay attention to the details, but if you don't have a grand vision, people won't know where you're going. Producing change is one of the hardest tasks, I believe, of leadership or of management. A reason for that goes all the way back to the statement by McAvelli who said that, I'm not quoting, but really the issue is that those who are opposed to change usually feel very strong about it and make themselves heard. And those who will be the beneficiary of change don't have that great a stake in that and are usually pretty quiet and so you have this disproportionate opposition to change. But if there's one thing I learned in my business career is that if you don't change, the people around you will change and you'll suffer from it and you have to constantly even be destroying your own current business, which is hard to do, but if you, for example, if you were in the film camera business, you'd better recognize early on that you'd better get in the digital camera business, even if it meant destroying your own market, because if you didn't, somebody else would get there first and be in the cat bird seat. Change is a challenge. The other big lesson I learned about making change, which is kind of intuitive I think. Many people argue that you should do it slowly, give people time to get used to the change and don't do anything that's too disruptive. I found that that's just exactly wrong, that if you're going to make big change, do it quickly, get it over with, and get on with life, get into the new mode. People could stand change, they just can't stand uncertainty.
