You are perhaps bang on the target Mr Kailash. You being the author of this thread, one can easily assume that you are an introvert. Partha has already admitted and I too am kind of an introvert, but definitely not the type that Partha has ascribed himself. So that makes us three of us. Even though I like passing time on my own, with my work, books or whatever, secretly I desire to be an extrovert. At least from the outside it looks nice to be able to mix up with people, have a small talk with them and all that goody-goody. But when it comes to actually doing it, I prefer to go my own way, because that's what I enjoy the most. Anyway I have long realized it's always better to be your own, accept yourself the way you are and be happy with that.
Yes, I too concur with ar, that most of us might be somewhere in the middle of the scale, neither introverts nor extremely extroverts. Somewhere down the line, there could be a link between online activity and the nature of a person. Not those who are professionally engaged, but the ones who take it as hobby or entertainment are likely to be or become introverts. The reason could be quite apparent; less interaction with our peers, friends and family.
Patience and perseverance pays
