"There is so much about my fate that I cannot control, but other things do fall under the jurisdiction. I can decide how I spend my time, whom I interact with, whom I share my body and life and money and energy with. I can select what I can read and eat and study. I can choose how I’m going to regard unfortunate circumstances in my life-whether I will see them as curses or opportunities. I can choose my words and the tone of voice in which I speak to others. And most of all, I can choose my thoughts."
