Good ideas never come in bunches

"One of the more common sources of doubt and confusion is the inexperienced and anxious executive who innocently expects, or even demands, to see not one but many solutions to a problem. S/he needs the reassurance of numbers and an opportunity to exercise s/he personal preferences. Simplistically, a profusion of ideas assures a profusion of choices, but only one of them can be the most appropriate. The practice is as bewildering as it is wasteful. It discourages spontaneity, encourages indifference, and generally produces results that are not distinguished, interesting or effective. In short, good ideas rarely come in bunches."
