You know how mountain climbers get up Everest or marathoners get through Boston? One step at a time. They don't think about the big picture, they think about making it through the next stride or step. When you're facing a seemingly insurmountable task, do the same thing. Instead of thinking about your stressor as one insurmountable hurdle, break that unmanageable task into smaller, more manageable ones. Those are the ones you can accomplish. Before you know it, you'll have reached 29,035 feet.
