A life lesson for me is, how do you muster the courage to take on a new risk? Whether it's starting up a business or taking on a new project or expedition. I think the risks that we take are all relative to the risk-taker.

This journey is not over. Our education initiatives have so much momentum, and we're committed to sharing even more stories from the Arctic when we return.

I get stubborn and dig in when people tell me I can't do something and I think I can. It goes back to my childhood when I had problems in school because I have a learning disability.

I had no doubts I could go to the pole. I may not be as strong, but I make up for physical strength in other areas, like steadiness and not panicking under stress.

I wanted to be a teacher, but I was a lousy student, one of the slowest readers. It was a tremendous struggle. But I'm lucky I had some teachers who saw something in me.
