Some one from Bangalore asked in Quaro if he should take up a high-paying job in the US. Most answers point to go-ahead but below answer serves me a consolation prize. I think I have a pretty good life:)

May be My answer seems stupid. Anyway i am telling you this.
Answer few of my questions and you will get the exact answer you need.
1. How much more years you are going to live?
 50, 60, 70
2. How much more years your parents going to live?
20, 25
3. How much more years you are planning to spend together with family ?
5 ,10
We cannot save years ahead, we can save the moments. Hence take a short plan.
GO there. Work hard, Earn well for maximum 5–7 years.
Come back be stick with family.

If you are getting enough income right now , dont think about losing moments.
I have many friends , who are abroad with tons of money in accounts but not getting the exact happiness they expect in life.
Think and decide dude.
All the best.
