One decision...

It is tremendous how history is full of great and horrible events, and there has always been a simple decision which started it all off. In my talk, I want to look at the repercussions of decisions made around us and how they affect us directly. People of small rank get affected by the decisions made by those of "important" ranks. I want the audience to think about how their decisions may essentially have a negative, as well as positive effect on someone else's life.
