Sidney Crosby

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.

You make your first album, you make some money, and you feel like you still have to show face, like 'I still go to the projects.' I'm like, why? Your job is to inspire people from your neighborhood to get out. You grew up there. What makes you think it's so cool?
