When the body gets tired, when the winds pick up and hit you head on, when getting out the door for today's first mile seems harder than finishing yesterday's last mile, when the rain comes down in sheets, or sleet pelts you from the side and makes the skin of your legs sting, when you've given it everything you have and your body screams there's nothing left to give...you've got to ask yourself one question: How bad do you want it?
