What changes have you seen in you since you started running?

There are few experiences in life in which my physical and psychological abilities are as sharply defined as they are during marathon training and racing...The training and racing experiences have shown me sides of myself that I never knew existed. I've found perseverance, an ability to focus, stubbornness, compulsiveness, bravery, organization, a sense of humor, and a capacity for unbridled joy.
