A. Do you think it’s possible to have a happy family and a successful career at the same time?

To do so, the husband should be willing to do household chores / house works after his job. When the wife is in-charge of housework alone, she is never happy.  She is just exhausted at home. How about raising a baby? This is a lot of work for a woman to do. But nowadays, people push them to have a super power in the world. It is like money is everything these days. I know the word DINK (double income, no kid).
