it does not require great deal of planning to manage time for your work or your family. Don't bring work at home amd don't let home be with you at work. Work hard on weekdays and Enjoy 2 days of weekend with your family. One spend 8-12 hours at work, just look at your schedule and see how constructively you use these 8 - 12 hours. Not to be surprised that you work only 5- 6 hours. manage this time and see how easy it is to maintian the balance
