If its for the family or desire to do something back in home town then going back for good is one of the good decision of a lifetime. Although if it is for your friends and environment of the city that was in pause mode in our mind since we all came abroad, then going back for good is one of the worst decision. One other thing to keep in mind is to ask yourself what do you want to do or achieve in this lifetime? Do the same monotonous thing over and over (wasting your potential) and make others rich here or do something and contribute back home? Decisions and decisions.
