Strategic Statement: This is serious question, and your response should be put in a manner that promotes follow-up questions or continued discussion.
Sample Response: As I mature, I find my list of responsibilities grows and gets more complex. The responsibilities become loftier and larger. My strategies for keeping my personal and professional life in balance work up to the point that things change in my personal and/or professional life (the change and expansion in responsibilities)... at which point everything has to be re-calibrated. I suppose that it’s an area that I will always be improving upon... I see a balanced life as critical!
