Except one who had the courage to admit, I don't know. The question doesn't have an answer. And it wouldn't matter if it did. But most executives, teachers, policeman, consultants, journalists, politicians, and parents find it difficult to admit ignorance. Editors think they have to improve every article that crosses their desk.
Managers lose sleep at night thinking of ways to direct their subordinates.
And every member of every committee feels compelled to make a contribution to the program whether the program needs it or not. Too many creative efforts are sabotaged by managers sending their people on search missions for a solution they secretly believe they already have. No one has all the answers . Most of us don't have most of the answers. Some of us don't have any answers.
