with all the over time and stesses in life... how do you balance work and family and your own personal time?
It all Depends on One's own need and Mind SET.
If he wants to grow Professionally to a Great Height - Better Don't commit urself with sibblings.
You can move ahead and Spend a Happy Life with EQUAL contribution of your TIME towards your FAMILY and your WORK.
Ofc, Family makes us Much Happier than WORK. Happiness in Work is for Some few Minutes. Happiness that you get from ur Family and Sibblings may even LAST for ur Life Time.
In my Personal Opinion - Family should be given more Priority.
Yes, this is very difficult indeed. I tend to reserve enough time for myself and I'm being a bit selfish now and then. Most of the time I spend time for myself in the evening. I get some peace and quiet in the hours after dinner.
