constructive ego

While reading a friends blog recently, I encountered this term constructive ego (CE). I must admit, I have been fascinated by this term since. My friend recommended that you should have a healthy dose of it. I used to refer to this friend as a "snob" quite often back in the days and so followed a chain of thoughts and I ended up thinking that what is ghamandi (snob) for me is maybe constructive ego (CE) for him. But the more I pondered, and did introspection to find out where my constructive ego is, the more it got clear that snob is completely different from CE and I probably suffer from a deficiency of CE.

The second reason chain of thought is, if I am right about this concept, why do I lack it? I seem to lack it more in my personal life rather than professional life. I could identify scenarios form my professional life where this constructive ego helped me withstand pressures and present my ideas effectively. But in personal life, I could not think of any scenarios where I could identify me using this CE to put forward my ideas or points. The lack of it always makes me go through pain and suffering. Some of my close friends all seem to have it including my wife. From all this introspection, I think constructive ego is a good thing to possess and in the times we live it helps us all to deal with life.
