“What other people think of me is not my business.”

“Listening to people espouse beliefs different from mine is informative, not threatening, because the only thing that can alter my worldview is a new and undeniable truth, and contrary to what Jack Nicholson says in 'A Few Good Men', "I CAN handle the truth.”

“I am careful not to confuse excellence with perfection. Excellence, I can reach for; perfection is God's business.”

“To be brutally honest, for much of that time, I was the only person in the world with Parkinson's. Of course, I mean that in the abstract. I had become acutely aware of people around me who appears to have the symptoms of Parkinson's disease, but as long as they didn't identify with me, I was in no rush to identify with them. My situation allowed, if not complete denial, at least a thick padding of insulation.”

“When describing me, Tracy often refers to a well-known concept of physics: 'inertia.' As Newton avers in his first law: 'An object that is not moving will not move until a force acts upon it. An object that is moving will not change its velocity until a net force acts upon it.' In other words, depending on what's happening in my life at any given moment, I can either be the laziest human being on the planet, or the busiest. I'm perfectly content to do absolutely nothing until I'm catalyzed by some person or project, and then I go nonstop until some countervailing force acts upon me, and I revert back to static mode.”

“I think I benefited from being equal parts ambitious and curious. And of the two, curiosity has served me best.”

“Personally, I didn't take a single photograph while I was there, but that's not all that unusual for me. I suppose my aversion to snapping pictures may have something to do with shaky hands and blurry results, but there's another reason: The act of lifting up the camera and positioning it between me and the object of my interest separates me from the experience.”
