the greatest people aren't disciplined, they are obsessed
inspiration
inspiration is fleeting, exciting, and bright. it sparks action but fades as quickly as it comes
motivation
motivation is deliberate, energizing, and focused. it pushes action, but needs constant renewal
discipline
discipline is controlled, grinding, and rational. you do something because you've decided to not do anything else
obsession
obsession is primal, unintentional, and emotional. you do something because you can't do anything else
