This thought has crossed my mind too very often. Not because IT is overwhelming, but more because of boredom. I look inside myself to see and all I get is nothing. I know I cannot be a doctor, but there is a host of other professions. I am very interested in Law and am seriously contemplating. That is quiet feasible too, if one is really motivated. Other options are Management.( Sales, Finance etc ). The only catch being the cushy life that one has now has to go as it is like starting afresh.
I know of one extreme case too. One of my class mate, engineering graduate worked in an Auto majore in their Styling dept for more than 4 years. But developed interest in Cinematorgraphy, took pains and finished his Diploma in Pune Institute of Film Technology. 3 years course he did and now started a new career in Chennai as assistant to PC Sriram. He is still lying low but some day he will hit it big and then I can proudly say, "Hey, I shared my dosa with him at Pune", while I might still be drudging myself in technology..
It all depends on what one's ambitions are, what price one is willing to pay.
Every dog has its day. Today is my day.
