The children need serum from the outside world if they are to survive. Their only hope is a few chosen Eskimo drivers and their teams of dogs.

On the verge of quitting, she took a chance and moved to the high altitudes of Alamosa, Colorado, where legendary coach Joe Vigil had started the first professional distance-running team. There she encountered the idea that would transform her running career: the notion that changing her thinking - shaping her mind to be more encouraging, kind, and resilient - could make her faster than she’d ever imagined possible.

This is more than just an audiobook. It's an attitude. It's a mentality. It's a lifestyle. The F*It List is my journey, my life, my lessons, my successes, and my many failures...in my own words.

It allows you to stand up for what you believe but also helps give perspective on external situations and opinions outside of your control. It's not always comfortable, and in many instances, it is downright scary. Yet, instead of searching for the meaning of life, you will be authentically living it.
