Did your teachers recognize that you had a special talent? Did any of them take a real interest in you?
Robert Ballard: To most of my teachers I was just a pain in the neck, because was hyperactive. I was all over the place. That can be disruptive. Most people would rather say, "Slow that guy down or get him out of here." Fortunately, there is always one out of a hundred teachers who loves that characteristic. Those are the people that always encouraged me. At every critical point in my life, when I was ready to quit, I can point to someone, who said, "Keep it up."
You are always going to be criticized if you're a doer. You have to make sure you know who to listen to. You need to pick out certain people you have great respect for, and listen to them. I've always had those mentors throughout my life -- whether it was in the Navy, business, academia, even in sports -- that I listened to.
