Well, Raghuveer, I guess the first thing I should say to you is congrats! Although I have to admit that there's part of me that is thinking that somehow, this is not really the best thing for you, or better, not the "ideal" situation for you.
But in life we rarely have the option to choose that which is "ideal," nor is any one of us really able to figure out precisely what "ideal" would be, anyway. As others have said, you are both very young and very bright, meaning you still have enormous potential for what you could achieve in the many, many years of work and study that lie before you.
I trust you will excel in an MBA program; that's a given. What I wonder, though, is whether you will become passionate about. I have a sense somehow that, should you indeed pursue this course of study, you will excel in the program, find a good job after finishing, and then, after a few years of working, decide to pursue either a second Master's or a Ph.D. You seem to be a natural academic, and I sense that you will always enjoy the more theoretical aspects of whatever you do. These are merely my opinions, formed over the last year and a half of watching you participate, try your best (with humor, kindness, gentleness, and always, a sharp intellect). I may be completely wrong, though.
I know you are financially committed, but perhaps your options are still open? Who knows? You may just get a juicy offer from a school here that you can't turn down. I would hope that you would remain receptive to other paths your future may take.
So again, Raghuveer, congrats. I have full confidence that no matter where you go and what you study, you will excel. And I do hope you can make it to the States one day (perhaps as a guest lecturer?
).
