When you get a typical injury, you're given a time frame; you're gradually working towards getting back. With concussions, there is not generally a time frame or a span where you're feeling better. You feel like you're getting better, and it can be one day and you're back to where you started.

I think every athlete will tell you no matter what sport you're in, when you train so hard and when you care so much about doing what you do, there's a little bit of nerves that come with that. But nerves that won't prevent you form performing, nerves that, hopefully, allow you to be that much more motivated and inspired to do well.

When people said Africa would change me, I didn't understand what they meant. To see the poverty in the townships, for instance, is overwhelming. I found it heart-wrenching to see young children walking barefoot and hungry in the dirt. I'm the kind of person who wants to change the world right here and now, so I got frustrated.
