What is your significant contribution in our society?

I'm sorry, this question calls for "your" contribution, what you believe is the most significant of "your" contributions to society. I'd like to think that I have raised my children in a way that has provided them with active, positive ways with which to serve their communities.... that I have instilled values in them that will guide them throughout their lives. I also help that in mentoring my students, I have provided that same type of guidance.... that I've made a difference.
