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.
There are a lot of things to consider if you are planning to work abroad. Also, it entails a lot of sacrifice for the part of the family. Life is too short to spend time apart just to earn much money. What is more slapstick reality is that at the end of the day you cannot really turn back time if something happens to any member of the family.
