When you're running and you are there, there's a little person that talks to you and that little person says “Oh, I'm tired”, “My lounge's about to pop”, “I'm so hurt”, “I'm so tired”, “There's no way I can possibly continue”. And you wanna quit. Right? That person, if you learn how to defeat that person when you're running you will learn how to not quit when things get hard in your life.
