The middle east will eat your soul, it will make you sign up to subscriptions for stuff you would never think about back home but which cost a lot of money. You will become dependent on the salary because of obligations you got yourself into cause you must ; bond, overpriced rentals of real estate , car loans , just to give you and your family a half decent lifestyle in the midst of the 3rd world society that you will learn to hate. The middle east is good if you already have a secure home and a place to escape when they fire you over a minor mistake no matter how many years you have sacrificed your health to fly their slavery rosters. All in all , the best experience you will take from it is that you will - from the moment of your final expit permit, respect your home and the civilisation you are coming from.
