At the drop of a hat
Do you switch off your mind from work, once you leave your office? You should. If you keep thinking about pending work, then you are spoiling your personal life.
Try imagining 2 hats. Work hat and Home hat. When you are in office, you are wearing the imaginary Work hat. As soon as you finish your work and step out of the office in evening, touch your head and change to Home hat. The Home hat will not allow office thoughts to enter your mind. Relax with your family till next morning.
Next day, wear your Work hat and go to work.
