According to Rasmussen Reports [1] a survey of 1800+ US workers…
92% of Managers rate themselves as “Good” or “Excellent”
BUT…
only 67% of employees say they work for a manager that is “Good” or “Excellent”.
That gap is what I call the “perception is reality” gap. You are (in general) what others think you are. For a CAD Manager that means that you need to keep in mind the way people perceive your talents. You may want to start asking around.
