I work 8 hours per work day, of which I have 4 per week. In the morning I bring my kids to school, on Friday I pick them up from school, because that's my day off. My wife picks them up on her day off: Wednesday. Other days, they're picked up by afterschool child care, and my wife picks them up there when she gets home from work.

I've got a day with the kids, she's got a day with the kids, we've got a weekend with the entire family. On Thursday evenings once every two weeks, we get a babysitter and have an evening for the two of us.

I completely neglected exercise until recently (I'm 44), but since a few months I'm doing cross-fit twice a week (aiming for 3 times).

Main productivity trick: sleep well, keep work hours limited so you can give it your undivided attention during that time.
