I was fortunate to have a grandfather who was an optometrist. Vision therapy was something that we routinely did to strengthen our eyes and give us better focus. I was fortunate that he could teach me techniques that are still paying dividends for me to this day.

My dad used to give me a lot of spankings. Anything I did wrong, he was on me. I was raised by a strict disciplinarian. He kind of laid down the law.

I was very fortunate to have some great mentors. A father that was always in my life set the example every day at home. Everybody asks me, 'What was your role model?' My role model slept 20 feet from me every night. I could always go talk to him and ask him questions no matter what it was about.

I can never let the guy across from me be in better shape. I have to be the best-conditioned guy.

It's not just vision therapy, it's occupational therapy, ... The fact that they have visual impairment doesn't mean they have to be stuck at home.

This allowed us to look at the Moon with new eyes. We haven't had ultraviolet vision before to do this.
