In light of Sarah Burke's passing, we revisit Gretchen Bleiler's heartfelt article about the risks of pursuing your passion in extreme sports. She writes, "I think Sarah would tell all of us to keep going, keep waking up early to land those tricks you've been dreaming of, but only if it's done with 100 percent passion, pure fire, discipline and commitment." Our sincerest condolences go out to the Burke family. http://w.espn.go.com/espnw/athletes-life/7461820/
