How difficult is it to juggle a career and raise kids at the same time?

That just depends on what your career is. If you like to bring a certain amount of work home, or at least 'think' in your time at home about work then FORGET IT if you have kids. It's ok at first but they become more & more demanding of time & attention.

When working & looking after kids too you "NEVER STOP!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
