Because when you give too many f*cks you will feel that everything is supposed to be just exactly the f*cking way you want it to be. This is a sickness. And it will eat you alive. You will see every adversity as an injustice, every challenge as a failure, every inconvenience as a personal slight, every disagreement as a betrayal. You will be confined to your own petty, skull-sized hell, burning with entitlement and bluster, running circles around your very own personal Feedback Loop from Hell.
