There have been many moments over the last year when I thought it was all over.

I've worked really hard, but it's definitely not been easy.

I would love to do well one last time in Melbourne and my dream would be to win Wimbledon and play in the London Olympics.

I've been practicing for a while now and physically trying to get in better shape as well after the injuries.

It wasn't like I ever said, 'I want to be an actor.' I was in the right place at the right time. I went to a local drama group because I found football on the weekends too cold - which is highly ironic because I've had some of the coldest experiences of my life filming 'Game of Thrones.'

As a physician, I'm somewhat an advocate of patients. How come, before Mike Webster, no NFL player was told or knew that there was an intrinsic risk of brain damage from playing football?

Many tennis coaches are enablers. They need the job more than the player needs the coach, and if the coach needs the job more than the player needs the coach, he can't effect change.

My football career was so filled with energy and impactful, as a University of Miami player and the things I did in Canada, that I left a good mark. I left a good impression.
