Paul: Something that I have often thought about is, after seeing some people who get so frustrated by what they refer to as their ‘own lack of motivation’, how do past experiences drive internal motivation? I seem to see people that I look up to as having really hard experiences growing up and this makes them very hungry to push further and harder than their competition. I wonder if motivation is driven by external or internal factors? Past experiences, nature vs nurture... etc. What are your thoughts?
