If you can come with a number in mind and can live within your means then you can get what you want and leave. Don't expect anything more from this place except money. The guys who can't save are those that have no plans and need to keep spending to satisfy themselves.
If you are the kind of person that needs a lot of external stimulation in life to be happy like concerts, beautiful scenery (haha not.mucj of that here), restaurants and all within the framework of your own society then you will be sorely disappointed.
If however, you can basically live in a fashion that doesn't need too much external stimulation but one in which time with friends, movies, books a few holidays per year etc. will be fine then you should be ok.
The issue is that individuals who have no business leaving their own societies and cultures but get tempted by the money show up and realize that life outside of their country is not the same everywhere else in the world and then bitch about it. They also fail to realise that actually living somewhere is different from going on holiday to that place, they therefore try to make their life into a holiday and it all goes wrong from there.
Maturity and a good understanding of where it is you're going and what your life is going to be like is the key here. There are plenty of people that bitch and moan but end up spending 15-25 years here.
