What would you do if you received a very attractive job offer from another county but your family simply couldn't follow you?

Yes, I would. If the reasons to leave them is for their own good to provide their need interms of financially.

" The one doesn't gain everything " this is true.

I'll obey my family's desire.

Take the job offer as long as its good for me …be in touch with them all the time via skype and facebook ….use every vacation I get to see them !

Time! Time! Time! . Everything will work out  if you give it time. First thing to do is, take the job.                   And gradually let your family  fall in love with your new enviroment . You can start by making sure the come for holiday and find activities they will enjoy doing. But do not give up on a good opportunity for a great job. You will be alright.

Opportunity knock once.  It will be a tough decision to make.  Lots of children went astray due to lack of parental guidance but if u will be able to explain to your children the necessity of leaving home for work... they will understand.  i'd rather grab the opportunity,   to be able to give my children  what they need in life and teach them how to value the hard earned money so that in the future they wont have to leave home just earn money and live comfortable life.

My family is my duty 

I work for them 

And would love to have my children and my wife with me anywhere. 

So work hard and out to the same level for the job, which nominated her

I would think of more than just the career, the quality of my life and the quality of my family's life. My decision would be based on the happiness and security of all the family members including myself, both now and in the future. There is more to life than just career, the career is a means to support your lifestyle and not solely your life. 

Depending on the circumstances my decision could go either way, but would be based on quality of life and overall happiness of everyone in my family. 

We should not ignore realities of life.  You have a family who no know you in full, your talent, exposure everything.  If the job is challenging to be attractive and if you feel that it will turn to be a mile stone and turning point in your life you can positively proceed with. You are only click / just few hours away from them and the whole world has become so close and very near as if your home town.

depends on circumstances. But life is name of balance b/w family and work. I would say yes to job unless n until my family is there with me. :)
