Take a picture of yourself. Look at the photo. If you see a reasonably successful man in his mid 40s with a few more wrinkles and perhaps a little less hair, a keen look in his eye and a wry smile that says he's been through a lot but remains optimistic about his job, then you are the spitting image of the typical Control Design reader who responded to our fourth-annual salary and job satisfaction survey.Granted, how "successful" one feels is entirely subjective, but salary is one aspect that most of us agree offers a common, bottom-line measure of our personal self-worth and professional prosperity. This year, respondents reported their median average annual salary was just over $71,000. Not surprisingly, that figure, in practical terms, is little changed from salary averages reported by our three prior surveys ('01: $67K, '02: $66K, '03: $72K).
