#1. Schedule time for family. It's just as important as work. Plan ahead. It's so much less stress on your head once the plan is in place. Plan quality time with kids, perhaps homework help and a interesting story before they go to to bed. Quality time with your spouse is critical. Plan that much sort out date months in advance.
#2. Plan for you personal down time. I find my passion and creativity where I zone out of the present. To each his/her own zeal.. Poker nights, fishing trips, a guys only vacation 2-3 days, long bike rides etc. You'd come back completely refreshed.
