This week brings the Opening Ceremonies of the 2018 Winter Olympics in PyeongChang, South Korea. The Olympics is a marvel of the modern world, a remarkable moment when people from nearly every country in the world can join in one place and compete for personal and country pride in a fun, peaceful atmosphere.

But the feeling of peace that permeates the Olympic spirit doesn't mean these athletes don't feel fire in their hearts. These athletes are warriors, forged in years of dedication and sacrifice to achieve their goals. Even those who fall short of a medal can still count themselves among the very best in the world.
