Taking pride in ignorance First and foremost, concentrate on your strengths. Put yourself where your strengths can produce results. Second, work on improving your strengths. Third, discover where your intellectual arrogance is causing disabling ignorance and overcome it...First-rate engineers, for instance, tend to take pride in not knowing anything about people. Human resources professionals, by contrast, often pride themselves on their ignorance of elementary accounting or of quantitative methods altogether. But taking pride in such ignorance is self-defeating. Go to work on acquiring the skills and knowledge you need to fully realize your strengths. Peter F. Drucker, Managing Oneself ignorancearrogance
Essential vs. nice to have Customers have trouble distinguishing between essential features and those that are just "nice to have." Examples of the latter class: those arbitrarily overlapping windows suggested by the uncritically but widely adopted desktop metaphor; and fancy icons decorating the screen display, such as antique mailboxes and garbage cans that are further enhanced by the visible movement of selected items toward their ultimate destination. These details are cute but not essential, and they have a hidden cost. / Increased complexity results in large part from our recent penchant for friendly user interaction. I've already mentioned windows and icons; color, gray-scales, shadows, pop-ups, pictures, and all kinds of gadgets can easily be added.
