I am frightened by this quote. The fact that we are defined by opportunities, including the ones that we missed, is a sobering thought. Quite frankly, it is one that I had not considered.  I had always reflected upon my life by the opportunities that I had taken never considering that the opportunities that I missed also shaped my life. I can now look back over my life and see that I was affected just as much by the opportunities that I missed.  From now one, Carpe Diem!  I hope to seize every plausible opportunity that comes my way!
