Got to say I thought it was odd he didn't move his family over here
On one level I get it 'cos you don't want to disrupt the kids schooling. On another level, it shows he either didn't understand how massive the job is or didn't want to fully commit.
You need to throw yourself into it to have any chance of succeeding. If that means bringing your family over with you so you don't have to engineer 2-3 day breaks in training so you can pop home, then just get it done.
