In fact, it is one of most difficult question, I ever had. I had these thoughts million times but every thing in life is relative, means six years ago probably you have single mission, just tough the country of oppertunity, USA. After six years, you need is different than before. At the same time, lot of things are situational, more the people like us, who had lot of restrictions, either by immigration or family or a way we grow up. One of the major factor is age. If you come in undergrad, probably you might be more comfortable with this system. But when you come in graduate, then even if you have better life comparatively than undergard because you don't have to do that much struggle but still you have a gap in society, you feel more lonely, more responsible and more different than this society.I feel preety old fashioned, definitely I had been to bars and clubs, seen every aspect of life but never feel, it is my part of life. I always feel I am some what at the pavement, not in a main road. Ok, I came to do master's engineering, done, had good job, wife's visa rejected, going to quit this job, apply phd and got scholarship and going back home and try for both, let's see what would happen.
