I agree, You will also feel the importance of your family's presence when you are alone in other country working. The sacrifice of being away from them just to give them a better life is one of the way to show them how much we love them. Sadly, there are family members who also take advantage of the person who is working abroad. My prayer is that all of the people can stay in their own country with better opportunities so that they don't have to leave their families. Its not always about the money we can give but also our presence and time to bond with them.
Working outside the country it more sacrifices. Because homesick is the one your enemy, here in my country there are a lot of people go for other country to work.
