I do everything I do to pay tribute to my great-grandfather.

The impossible is not quite impossible if you put your mind to it.

It's Niagara Falls. It's one of the most beautiful natural wonders in the world. Who wouldn't want to walk across it?

The mist was so challenging and the winds hit me, definitely more than I expected. It was definitely those winds, you can't re-enact them, you can't recreate them. Then my forearms started to tense up and you feel like running.

What I'm doing is a natural wonder. If not, there'd be 150 people behind me on the wire.

What an incredibly beautiful city at night Chicago is. Absolutely beautiful.

I've trained all my life not to be distracted by distractions.
